I have yet to find a good way to do this myself.
It seems it is an issue that really needs some written best practices
though, since a lot of libraries that define result appear to not to it
vert well (sadly, even Phoenix is among them; it uses more
specializations than necessary and simple things like result_of<F(int,
int, int&)> are ill-formed).
