Hi there,

I've used this metafunction for some time, and it just fitted my need. Recently, I make up my mind to complete it, willing to put it in public.

Synopsis -------------- can_be_called<F, Sig>

F Any callable type to test, even member-function ptr. Sig The desired calling signature, function-type only.

Personally, I've found it more useful to just not define result_of<F(args)>::type if F(args) cannot be called.
