Good to know. In that case, "just use `equal?`" is probably good advice
for new Racket people.
Personally, I'm super-comfortable with `eq?` for symbols (since, as you
know, it's a basic thing that's been used very heavily in Lisps for
old-school AI and compilers and such). So I might as well keep
efficient Scheme portability in this particular way, even were Racket to
officially guarantee that `equal?` is as fast.

FWIW, if you use equal? in those cases, you'll get the same
performance behavior and you will have fewer eq?s to audit when things
go wonky.
