It would be has_operator<T, U, boost::type_traits::any>
Then boost::type_traits::any_return would be more appropriate.

I prefer void because it is shorter but this could make people think
it will check for operator return void... which is not the case; so
maybe the long version boost::type_traits::any_return is better.
