AFAIK, since type resides in the base class, which is a dependent type, the compiler won't look in the base class for type; it's looking in namespace scope and there's no type at namespace scope. So you either need a using declaration or explicit qualification. (Some versions of MSVC, at least, happily but incorrectly accept the above code.)
Sorry, no references handy :(
You are correct. I should have realized this, but the MPL book suggestions metafunction forwarding so I used it.
