Hello.

Recently I looked for type_traits for callable classes. It so strange, I
didn't find such traits. Most likely, I just missed them or something like
them.

I actually don't know is there a real need for them. Anyway I tried to
write such traits at least for practice and metaprogramming training. I
tested them with gcc, clang and msvc2010. I would appreciate if you looked
at the code. Here is the
link<https://github.com/AntonBikineev/is_functional/> to
my github repository.

It's cool that they can see hidden generated operator() of lambdas closure
type.

Best regards, Anton.
