No more bloat than in the rest of the language ;)

I *assume* that this will have trouble making it in to 7.1, and since
keywords are likely added this may have trouble with 7.1.x (not sure
about that; perhaps the lex-generated token values never make it into
the database tables, but they *do* propagate into structures used deeper
in the backend).
