Ok, so

        struct Map { template<typename T> struct apply { typedef int type;
}; };

is a "lambda expression" then? A bit weird in my book, but if that is the
official nomenclature for MPL, I will use it...

By the way, Aleksey, what do you think of calling anything applicable via
mpl::apply a "metafunctor"?
