A SFINAE-Friendly std::iterator_traits, v3
by Walter Brown
Excerpt:
This paper provides wording to reformulate the specification of
iterator_traitsso as to avoid a hard error when its template argument does not have the member types expected of a nonpointer iterator, and thus to make the trait conveniently usable in a SFINAE context.
