   *  This class provides similar behavior and semantics of the standard

   *  By default, a temporary_buffer<Iter> stores space for objects of
   *  whatever type the Iter iterator points to.  It is constructed from a
   *  typical [first,last) range, and provides the begin(), end(), size()
   *  functions, as well as requested_size().  For non-trivial types, copies
   *  of *first will be used to initialize the storage.
   *
   *  @c malloc is used to obtain underlying storage.
   *
   *  Like get_temporary_buffer(), not all the requested memory may be
   *  available.  Ideally, the created buffer will be large enough to hold a
   *  copy of [first,last), but if size() is less than requested_size(),
   *  then this didn't happen.
