Lookahead is a better solution than delaying diagnostics and not caching
linkage. :) We’d need another arbitrary-lookahead tentative parser, because
the typedef name isn’t necessarily the first declarator, but the fact that you
can’t semantically have top-level expressions in there means that you can
indeed do this without incorporating semantic information from prior
declarators into lookup.
