   5 ``indirect_iterator`` adapts an iterator by applying an
   6 *extra* dereference inside of ``operator*()``. For example, this
   7 iterator adaptor makes it possible to view a container of pointers
   8 (e.g. ``list<foo*>``) as if it were a container of the pointed-to type
   9 (e.g. ``list<foo>``).  ``indirect_iterator`` depends on two
  10 auxiliary traits, ``pointee`` and ``indirect_reference``, to
  11 provide support for underlying iterators whose ``value_type`` is
  12 not an iterator.
