That would require extreme lookahead or reverting a lot of parser state, both
of which are not feasible. Nothing is obviously wrong here until we reach the
ill-formed call to ::Bar::thud, and that error is indistinguishable from the
nested name specifier on the call being wrong, which is what we say.

I don't think this is feasible for us to improve, unless you have some specific
suggestion for how we would detect the problem.
