Well, that would be how to distinguish them; we could define a new
token, say "QIDENT" to refer to quoted identifiers and leave "IDENT" for
the unquoted ones. Then a little work in gram.y should be enough to
finish the job.
The use of IDENT in gram.y is isolated to just a few places so
introducing QIDENT would be almost trivial afaict.
