class wpi::iterator_facade_base< DerivedT, IteratorCategoryT, T, DifferenceTypeT, PointerT, ReferenceT >::PointerProxy

A proxy object for computing a pointer via indirecting a copy of a reference.

This is used in APIs which need to produce a pointer but for which the reference might be a temporary. The proxy preserves the reference internally and exposes the pointer via a arrow operator.
