- * opt::copy - optimised for trivial copy (cf std::copy)
- * opt::fill - optimised for trivial copy/small types (cf std::fill)
- * opt::destroy_array - an example of optimisation based upon omitted destructor calls
- * opt::iter_swap - uses type_traits to determine whether the iterator is a proxy
- *                  in which case it uses a "safe" approach, otherwise calls swap
- *                  on the assumption that swap may be specialised for the pointed-to type.

-/* Release notes:
-   23rd July 2000:
-      Added explicit failure for broken compilers that don't support these examples.
-      Fixed broken gcc support (broken using directive).
-      Reordered tests slightly.

 //  Revision History
+//  04 May 05 Added operator class bool_testable.  (Sam Partington)
+//  21 Oct 02 Modified implementation of operators to allow compilers with a
+//            correct named return value optimization (NRVO) to produce optimal
+//            code.  (Daniel Frey)
+//  02 Dec 01 Bug fixed in random_access_iteratable.  (Helmut Zeisel)
+//  28 Sep 01 Factored out iterator operator groups.  (Daryle Walker)
+//  27 Aug 01 'left' form for non commutative operators added;
+//            additional classes for groups of related operators added;
+//            workaround for empty base class optimization
+//            bug of GCC 3.0 (Helmut Zeisel)
+//  25 Jun 01 output_iterator_helper changes: removed default template 
+//            parameters, added support for self-proxying, additional 
+//            documentation and tests (Aleksey Gurtovoy)
+//  29 May 01 Added operator classes for << and >>.  Added input and output
+//            iterator helper classes.  Added classes to connect equality and
+//            relational operators.  Added classes for groups of related
+//            operators.  Reimplemented example operator and iterator helper
+//            classes in terms of the new groups.  (Daryle Walker, with help
+//            from Alexy Gurtovoy)
+//  11 Feb 01 Fixed bugs in the iterator helpers which prevented explicitly
+//            supplied arguments from actually being used (Dave Abrahams)
 //  04 Jul 00 Fixed NO_OPERATORS_IN_NAMESPACE bugs, major cleanup and
 //            refactoring of compiler workarounds, additional documentation
 //            (Alexy Gurtovoy and Mark Rodgers with some help and prompting from

-<h3><a name="iterator_adaptors">The Iterator Adaptors Class</a></h3>
-
-Implementing standard conforming iterators is a non-trivial task.
-There are some fine-points such as iterator/const_iterator
-interactions and there are the myriad of operators that should be
-implemented but are easily forgotten such as
-<tt>operator-&gt;()</tt>. The purpose of the
-<tt>iterator_adaptors</tt> class is to make it easier to implement an
-iterator class, and even easier to extend and adapt existing iterator
-types. The <tt>iterator_adaptors</tt> class itself is not an adaptor
-class but a <i>type generator</i>. It generates a pair of adaptor classes,
-one class for the mutable iterator and one class for the const
-iterator. The definition of the <tt>iterator_adaptors</tt> class is as
-follows:
-
-<p>
-<TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 COLS=2>
-<TR><TD WIDTH=30 VALIGN=TOP></TD><TD>
-<PRE>
-template &lt;class Iterator, 
-          class ConstIterator, 
-          class Traits = std::iterator_traits&lt;Iterator&gt;,
-          class ConstTraits = std::iterator_traits&lt;ConstIterator&gt;, 
-          class Policies = default_iterator_policies&gt;
-struct iterator_adaptors
-{
-  typedef ... iterator;
-  typedef ... const_iterator;
-};
-</PRE></TD></TABLE>
-
-<p>The <tt>Iterator</tt> and <tt>ConstIterator</tt> template parameters
-are the iterator types that you want to adapt. The <tt>Traits</tt> and
-<tt>ConstTraits</tt> must be iterator traits classes.  The traits
-parameters default to the specialization of the
-<tt>std::iterator_traits</tt> class for the adapted iterators. If you
-want the traits for your new iterator adaptor (<tt>value_type</tt>,
-<tt>iterator_category</tt>, etc.) to be the same as the adapted
-iterator then use the default, otherwise create your own traits
-classes and pass them in <a href="#1">[1]</a>. 
-
-
-<p>The <tt>Policies</tt> class that you pass in will become the heart of
-the iterator adaptor. The policy class determines how your new adaptor
-class will behave. The <tt>Policies</tt> class must implement 3, 4, or
-7 of the core iterator operations depending on whether you wish the
-new iterator adaptor class to be a
-<a href="http://www.sgi.com/Technology/STL/ForwardIterator.html">
-ForwardIterator</a>,
-<a href="http://www.sgi.com/Technology/STL/BidirectionalIterator.html">
-BidirectionalIterator</a>, or <a
-href="http://www.sgi.com/Technology/STL/RandomAccessIterator.html">
-RandomAccessIterator</a>. Make sure that the
-<tt>iterator_category</tt> type of the traits class you pass in
-matches the category of iterator that you want to create. The default
-policy class, <tt>default_iterator_policies</tt>, implements all 7 of
-the core operations in the usual way. If you wish to create an
-iterator adaptor that only changes a few of the iterator's behaviors,
-then you can have your new policy class inherit from
-<tt>default_iterator_policies</tt> to avoid retyping the usual
-behaviours. You should also look at <tt>default_iterator_policies</tt>
-as the &quot;boiler-plate&quot; for your own policy classes. The
-following is definition of the <tt>default_iterator_policies</tt>
-class:

-<h3><a name="iterator_adaptor">The Iterator Adaptor Class</a></h3>
-
-This is the class used inside of the <tt>iterator_adaptors</tt> type
-generator. Use this class directly (instead of using
-<tt>iterator_adaptors</tt>) when there is no difference between the
-const and non-const versions of the iterator type. Often this is
-because there is only a const (read-only) version of the iterator, as
-is the case for <tt>std::set</tt>'s iterators. Use the same type for
-the <tt>Iterator</tt> and <tt>NonconstIterator</tt> template
-arguments.

-
-<p>
-Next we will look at some iterator adaptors that are examples of how
-to use the iterator adaptors class, and that are useful iterator
-adaptors in their own right.
-
-<h3><a name="transform_iterator">The Transform Iterator Class</a></h3>
-
-It is often useful to automatically apply some function to the value
-returned by dereferencing (<tt>operator*()</tt>) an iterator. The
-<tt>transform_iterators</tt> class makes it easy to create an iterator
-adaptor that does just that.
-
-First let us consider what the <tt>Policies</tt> class for the transform
-iterator should look like. We are only changing one of the iterator
-behaviours, so we will inherit from
-<tt>default_iterator_policies</tt>. In addition, we will need a
-function object to apply, so we will have a template parameter and a
-data member for the function object. The function will take one
-argument (the dereferenced value) and we will need to know the
-<tt>result_type</tt> of the function, so <a
-href="http://www.sgi.com/Technology/STL/AdaptableUnaryFunction.html">
-AdaptableUnaryFunction</a> is the corrent concept to choose for the
-function object type. Now for the heart of our iterator adaptor, we
-implement the <tt>dereference</tt> method, applying the function
-object to <tt>*i</tt>. The <tt>type&lt;Reference&gt;</tt> class is
-there to tell you what the reference type of the iterator is, which is
-handy when writing generic iterator adaptors such as this one <a
-href="#2">[2]</a>.
-
-
-<p>
-<TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 COLS=2>
-<TR><TD WIDTH=30 VALIGN=TOP></TD><TD>
-<PRE>
-  template &lt;class AdaptableUnaryFunction&gt;
-  struct transform_iterator_policies : public default_iterator_policies
-  {
-    transform_iterator_policies(const AdaptableUnaryFunction& f) : m_f(f) { }
-
-    template &lt;class Reference, class Iterator&gt;
-    Reference dereference(type&lt;Reference&gt;, const Iterator& i) const
-      { return m_f(*i); }
-
-    AdaptableUnaryFunction m_f;
-  };
-</PRE></TD></TABLE>
-
-Next we need to create the traits class for our new iterator.  In some
-situations you may need to create a separate traits class for the
-const and non-const iterator types, but here a single traits class
-will do. The <tt>value_type</tt> and <tt>reference</tt> type of our
-transform iterator will be the <tt>result_type</tt> of the function
-object.  The <tt>difference_type</tt> and <tt>iterator_category</tt>
-will be the same as the adapted iterator.
-
-<p>
-<TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 COLS=2>
-<TR><TD WIDTH=30 VALIGN=TOP></TD><TD>
-<PRE>
-  template &lt;class AdaptableUnaryFunction, class IteratorTraits&gt;
-  struct transform_iterator_traits {
-    typedef typename AdaptableUnaryFunction::result_type value_type;
-    typedef value_type reference;
-    typedef value_type* pointer;
-    typedef typename IteratorTraits::difference_type difference_type;
-    typedef typename IteratorTraits::iterator_category iterator_category;
-  };
-</PRE></TD></TABLE>
-
-The final step is to use the <tt>iterator_adaptor</tt> class to
-construct our transform iterator. We will use the single iterator
-adaptor version because we will not need to create both a mutable and
-const version of the transform iterator. The transform iterator is
-inherently a read-only iterator.  The nicest way to package up our new
-transform iterator is to create a type generator similar to
-<tt>iterator_adaptor</tt>. The first template parameter will be the
-type of the function object. The second parameter will be the adapted
-iterator type. The third parameter is the trait class for
-the adapted iterator.  Inside the <tt>transform_iterators</tt> class
-we use the <tt>transform_iterator_traits</tt> class defined above to
-create the traits class for the new transform iterator. We then use
-the <tt>iterator_adaptor</tt> class to extract the generated
-iterator adaptor type.

-<h3><a name="indirect_iterators">The Indirect Iterators Class</a></h3>
-
-It is not all that uncommon to create data structures that consist of
-pointers to pointers. For such a structure it might be nice to have an
-iterator that applies a double-dereference inside the
-<tt>operator*()</tt>. The implementation of this is similar to the
-<tt>transform_iterators</tt><a href="#3">[3]</a>. We first create a
-policies class which does a double-dereference in the
-<tt>dereference()</tt> method. We then create a traits class, this
-time also including a template parameter for the traits of the second
-level iterators as well as the first. Lastly we wrap this up in the
-type generator <tt>indirect_iterators</tt>, using
-<tt>iterator_adaptors</tt> to do most of the work.

-<h3><a name="reverse_iterators">The Reverse Iterators Class</a></h3>
-
-<p>
-Yes, there is already a <tt>reverse_iterator</tt> adaptor class
-defined in the C++ Standard, but using the <tt>iterator_adaptors</tt>
-class we can re-implement this classic adaptor in a more succinct and
-elegant fashion. Also, this makes for a good example of using
-<tt>iterator_adaptors</tt> that is in familiar territory.
-
-<p>
-The first step is to create the <tt>Policies</tt> class. As in the
-<tt>std::reverse_iterator</tt> class, we need to flip all the
-operations of the iterator. Increment will become decrement, advancing
-by <tt>n</tt> will become retreating by <tt>n</tt>, etc.

-<h3><a name="integer_range">The Integer Range Class</a></h3>
-
-The <tt>iterator_adaptors</tt> class can not only be used for adapting
-iterators, but it can also be used to take a non-iterator type and use
-it to build an iterator. An especially simple example of this is
-turning an integer type into an iterator, a counting iterator. The
-builtin integer types of C++ are almost iterators. They have
-<tt>operator++()</tt>, <tt>operator--()</tt>, etc. The one operator
-they are lacking is the <tt>operator*()</tt>, which we will want to
-simply return the current value of the integer. The following few
-lines of code implement the policy and traits class for the counting
-iterator.

-<h3>Challenge</h3>
-
-<p>
-There is an unlimited number of ways the the
-<tt>iterator_adaptors</tt> class can be used to create iterators. One
-interesting exercise would be to re-implement the iterators of
-<tt>std::list</tt> and <tt>std::slist</tt> using
-<tt>iterator_adaptors</tt>, where the adapted <tt>Iterator</tt> types
-would be node pointers.
-
-
-<h3>Notes</h3>
-
-<p>
-<a name="1">[1]</a>
-If your compiler does not support partial specialization and hence
-does not have a working <tt>std::iterator_traits</tt> class, you will
-not be able to use the defaults and will need to supply your own
-<tt>Traits</tt> and <tt>ConstTraits</tt> classes.
-
-<p>
-<a name="2">[2]</a>
-The reference type could also be obtained from
-<tt>std::iterator_traits</tt>, but that is not portable on compilers
-that do not support partial specialization.
-
-<p>
-<a name="3">[3]</a>
-It would have been more elegant to implement <tt>indirect_iterators</tt>
-using <tt>transform_iterators</tt>, but for subtle reasons that would require
-the use of <tt>boost::remove_cv</tt> which is not portable.
-
-<h3>Implementation Notes</h3>
-
-The code is somewhat complicated because there are three iterator
-adaptor class: <tt>forward_iterator_adaptor</tt>,
-<tt>bidirectional_iterator_adaptor</tt>, and
-<tt>random_access_iterator_adaptor</tt>. The alternative would be to
-just have one iterator adaptor equivalent to the
-<tt>random_access_iterator_adaptor</tt>.  The reason for going with
-the three adaptors is that according to 14.5.3p5 in the C++ Standard,
-friend functions defined inside a template class body are instantiated
-when the template class is instantiated. This means that if we only
-used the one iterator adaptor, then if the adapted iterator did not
-meet all of the requirements for a
-<a href="http://www.sgi.com/Technology/STL/RandomAccessIterator.html">
-RandomAccessIterator</a> then a compiler error should occur.  Many
-current compilers in fact do not instantiate the friend functions
-unless used, so we could get away with the one iterator adaptor in
-most cases. However, out of respect for the standard this implementation
-uses the three adaptors.
