### 2775. `reverse_iterator` is does not compile for fancy pointers

Discussion:

`std::reverse_iterator<Iterator>::operator->()` is specified to call `addressof(operator*())`, but it returns `iterator_traits<Iterator>::pointer`, which may be a fancy pointer type from which no conversion from `T*` is possible. It should instead delegate to the underlying iterator's `operator->()`.

Set status to Duplicate

Proposed resolution:

This wording is relative to N4606.

1. Modify [reverse.iter.opref] as indicated:

   >     constexpr pointer operator->() const;

   > > -1- Returns: `addressof(operator*())`.Effects: If `Iterator` is a pointer type, as if by:

   > > >     Iterator tmp = current;
   > > >     return --tmp;

   > > Otherwise, as if by:

   > > >     Iterator tmp = current;
   > > >     --tmp;
   > > >     return tmp.operator->();
