The trailing underscore syntax is typically used when a library
construct has semantics very similar to a language component which
uses a keyword. I.e. mpl::if_ is similar to the language if, and
mpl::int_ to the language int, except that mpl tools operate at
compile time. In this case, I think, the semantics is sufficiently
different (vector types instead of scalar), which should warrant for a
distinct and descriptive names.
