 <h2><a name="intro"></a>Introduction</h2>
      
-<p>The C++ standard [<a href="#references">1</a>] contains the definitions 
+<p>
+There are various ways to initialize a variable, in C++. The following
+declarations all <em>may</em> have a local variable initialized to its default
+value:
+<pre>
+  T1 var1;
+  T2 var2 = 0;
+  T3 var3 = {};
+  T4 var4 = T4();
+</pre> 
+Unfortunately, whether or not any of those declarations correctly
+initialize the variable very much depends on its type. The first
+declaration is valid for any <a href="http://www.sgi.com/tech/stl/DefaultConstructible.html">
+DefaultConstructible</a> type (by definition).
+However, it does not always do an initialization!
+It correctly initializes the variable when it's an instance of a
+class, and the author of the class has provided a proper default
+constructor. On the other hand, the value of <code>var1</code> is <em>indeterminate</em> when
+its type is an arithmetic type, like <code>int</code>, <code>float</code>, or <code>char</code>.
+An arithmetic variable
+is of course initialized properly by the second declaration, <code>T2
+var2 = 0</code>. But this initialization form usually won't work for a
+class type (unless the class was especially written to support being
+initialized that way). The third form,  <code>T3 var3 = {}</code>
+initializes an aggregate, typically a "C-style" <code>struct</code> or a "C-style" array.
+However, the syntax is not allowed for a class that has an explicitly declared
+constructor.  (But watch out for an upcoming C++ language change, 
+by Bjarne Stroustrup et al [<a href="#references">1</a>]!)
+The fourth form is the most generic form of them, as it
+can be used to initialize arithmetic types, class types, aggregates, pointers, and
+other types. The declaration,  <code>T4 var4 = T4()</code>, should be read
+as follows: First a temporary object is created, by <code>T4()</code>.
+This object is <a href="#valueinit">value-initialized</a>. Next the temporary
+object is copied to the named variable, <code>var4</code>. Afterwards, the temporary
+is destroyed. While the copying and the destruction are likely to
+be optimized away, C++ still requires the type <code>T4</code> to be
+<a href="CopyConstructible.html">CopyConstructible</a>.
+(So <code>T4</code> needs to be <em>both</em> DefaultConstructible <em>and</em> CopyConstructible.) 
+A class may not be CopyConstructible, for example because it may have a
+private and undefined copy constructor,
+or because it may be derived from <a href="utility.htm#Class_noncopyable">boost::noncopyable</a>.
+Scott Meyers [<a href="#references">2</a>] explains why a class would be defined like that.

+There is another, less obvious disadvantage to the fourth form, <code>T4 var4 = T4()</code>:

+The template <a href="#val_init"><code>value_initialized</code></a>
+offers a generic way to initialize
+an object, like <code>T4 var4 = T4()</code>, but without requiring its type
+to be CopyConstructible. And it offers a workaround to those compiler issues
+regarding value-initialization as well! It allows getting an initialized
+variable of any type; it <em>only</em> requires the type to be DefaultConstructible.
+A properly <em>value-initialized</em> object of type <code>T</code> is
+constructed by the following declaration:

+<p>
+The convenience class <a href="#initialized_value"><code>initialized_value</code></a>

+but robust against the aforementioned compiler issues.

+<h4><a name="compiler_issues">compiler issues</a> </h4>
+
+Various compilers haven't yet fully implemented value-initialization.
+So when an object should be <em>value-initialized</em> (according to the C++ Standard),
+it <em>may</em> in practice still be left uninitialized, because of those
+compiler issues! It's hard to make a general statement on what those issues
+are like, because they depend on the compiler you are using, its version number,
+and the type of object you would like to have value-initialized.
+Compilers usually support value-initialization for built-in types properly.
+But objects of user-defined types that involve <em>aggregates</em> may <em>in some cases</em>
+be partially, or even entirely left uninitialized, when they should be value-initialized.
+</p>
+<p>
+We have encountered issues regarding value-initialization on compilers by
+Microsoft, Sun, Borland, and GNU. Here is a list of bug reports on those issues:

+The class <code>initialized_value</code> provides a convenient way to get

+
+Suppose you need to have an initialized variable of type <code>T</code>.
+You could do it as follows:
+<pre>
+  T var = T();

+But as mentioned before, this form suffers from various compiler issues.
+The template <code>value_initialized</code> offers a workaround:

+  T var = get( value_initialized&lt;T&gt;() );
+</pre>
+Unfortunately both forms repeat the type name, which
+is rather short now (<code>T</code>), but could of course be 
+more like <code>Namespace::Template&lt;Arg&gt;::Type</code>.
+Instead, one could use <code>initialized_value</code> as follows:
