: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.

explicit or partial specializations of ``indirect_reference``]

``type`` is determined according to the following algorithm, where

``x`` is an object of type ``Dereferenceable``::
