Please, no more trait blobs! IMO you should separate the traits into
individual meta functions that works on all function pointer types. For
instance:

   function_arity<T>::type
     Self explanatory.

   function_signature<T>::type
     MPL sequence containing all types of the function signature,
     including return type and type of *this if T is a member function
     pointer.

And while we're at it, why not deprecate function_traits?
