Comment (by Raffi Enficiaud):

 Well, I am not sure that `mpl::vector` can handle, especially because a
 [https://www.boost.org/doc/libs/1_67_0/libs/mpl/doc/refmanual/variadic-
 sequence.html preprocessor value] that is limiting the variadicity is
 involved.

 I suggest this instead: I will keep the `std::tuple` internally, and
 slightly improve the API such that constructing a `std::tuple` is not
 needed (and instead any variadic template would do).

 What do you think?

 The argument checking is definitely a good thing to have, and you will
 have a more general API. It will not be faster in terms of compilation
 machinery since it will still involve `std::tuple`, at least internally.
