:Requires: For an object ``x`` of type ``Dereferenceable``, ``*x``
|
|
is well-formed. If ``++x`` is ill-formed it shall neither be
|
|
ambiguous nor shall it violate access control, and
|
|
``pointee<Dereferenceable>::type&`` shall be well-formed.
|
|
Otherwise ``iterator_traits<Dereferenceable>::reference`` shall
|
|
be well formed. [Note: These requirements need not apply to
|
|
explicit or partial specializations of ``indirect_reference``]
|
|
|
|
``type`` is determined according to the following algorithm, where
|
|
``x`` is an object of type ``Dereferenceable``::

if ( ++x is ill-formed )

return ``pointee<Dereferenceable>::type&``
