If the template argument is not a model of Forward Traversal Iterator, one can
|

still use a subset of the interface. In particular, <code>size()</code> requires
|

Forward Traversal Iterators whereas <code>empty()</code> only requires Single

||||
Random Access Iterators whereas <code>empty()</code> only requires Single

Pass Iterators.

<p>
|

Recall that many default constructed iterators
|
||||
are <i>singular</i> and hence can only be assigned, but not compared or
|
||||
incremented or anything. However, if one creates a default constructed
|
||||
<code>iterator_range</code>, then one
|
||||
can still call all its member functions. This means that the
|
||||
<code>iterator_range</code> will still be usable in many contexts even
|
||||
though the iterators underneath are not.

incremented or anything. Likewise, if one creates a default constructed
|
||||
<code>iterator_range</code>, then one have to be careful about not doing

anything besides copying. </p>
