cannot have overloads (in C++98) taking containers/ranges:

fn( Iterator first, Iterator last ) fn( Iterator first, Iterator last, Functor f ) fn( Range rng ) fn( Range rng, Functor f )

as the last overload is ambiguous. Concepts will allow this to be resolved as a Functor will not match the Iterator requirements :).

you can use enable_if on the latter and disable it the two types are the same.

Not if you happen to have a type that is both a valid range and a valid function object. Yes, that's a corner case, but it's the corner of a large floating block of ice. -- Dave Abrahams Boost Consulting www.boost-consulting.com
