SFINAE compiler troubles

Question

The following code of mine should detect whether T has begin and end methods:

template 
struct is_contai         


        

Answer 1

Stephan T. Lavavej has this to say:

Please note that it is technically forbidden to take the address of a Standard Library member function. (They can be overloaded, making &foo::bar ambiguous, and they can have additional default arguments, defeating attempts to disambiguate via static_cast.)

So I guess I'm going to use the simpler version that only checks for the nested const_iterator type.
