Hmmm, then I'd prefer a shorter "has_call" that'd fit in Operator Type
Traits better.
But do you think member-function ptr fits in this context? e.g.

    has_call<void(X::*)(), void()>::type // mpl::true_

To rule the doc style and include hierarchy, providing specific macros for
compile/preprocess, for example.
Otherwise I have to follow the convention of the parent lib...
