Actually, identity<> is also a fine name for a type envelope: it's used to
transmit the identity of a type, its parameter... and I'd rather have just
one template than two.
However, I know there was what seemed like rancorous objection when I
suggested identity<> before; nobody seemed to get the whole metafunction
idea, so for the record, I don't care all that much what we call it.
