I'd be inclined to prefer the first solution, because I just don't see
any advantage in the second one. Do you have some strong arguments in
favor of the second approach?

Yep I agree, I think we must consider metafunctions and free function
not as a goal or proof of good design but as a more powerful tool that
we can use if things go too complicated. Anyway, I'll give it a try to
compare the resulting code, on library side and (most important) on
user side.
