A SFINAE-Friendly std::iterator_traits

by Walter E. Brown


This paper proposes to reformulate the specification of iterator_traits so as to avoid a hard error when its template argument does not have the member types expected of a non-pointer iterator, and thus to make the trait conveniently usable in a SFINAE context.
