The compiler could do this with "--" symbols if we wanted to, I guess.

I'm not necessarily against this or anything, but I do like the "--"
convention, because it makes it very explicit what's internal and what's
not.  On the other hand, if we had tagging like this, we could also
make (say) font-lock react to this information and make it as obvious as
the "--" convention.
