Did you honestly think that I was refering to the *definition* per se, and
not the *defined entity* (Map)? ...

The reason that "metafunctor" is not that intimidating to more junior
(w.r.t. meta programming) is that they have learned the use of "functors" in
generic algorithms and such in C++. And it seems to me that things being
applicable via mpl::apply is the closest we get to that notion.
