Just out of curiosity, what's a "naive type vector"?

Well, iterators are separate templates, and require to be instantiated...
Also if you dereference them through meta-function, like
mpl::dereference<Iter>::type, that's one more instantiation.

(Not that I think it's critical for the typeof implementation)
