--- Comment #16 from Glen Joseph Fernandes <glenjofe at gmail dot com> --- > should a wording defect be raised against std::to_address(Ptr), to state that > pointer_traits<Ptr> being well-formed is actually a prerequisite? That's not an omission in the specification of to_address. The function is intended for pointers, and specified in terms of checking for a pointer_traits<P> member, and this means pointer_traits<P> must be well-formed. Adding an additional text to the specification saying this explicitly is unlikely to help anyone. The real change that users of iterators[1] would want is to make pointer_traits SFINAE friendly. [1] Users of pointers don't care much, since all the pointer types people are using with to_address(p) already have a well-formed pointer_traits<P>.
