landmark.el is unhappy with this (or vice versa):
landmark.el:1140:55:Warning: reference to free variable `s'
etc. It uses commas in function names.

Great, then let's fix landmark.el.
If we ever want to fully support new-style backquotes, we'll have to
disallow commas from symbols.

OK; done. (I wasn't sure if this was an intended consequence.)

You also have the alternative of distinguishing the first character
(ie, allow a different set of characters there).
On a related topic, has anybody ever run into an issue with lookalike
characters (eg, Japanese full-width latin and numerals, Latin A
vs. Cyrillic A vs. Greek A, etc)? Unicode alleges this to be a
security risk. (The reason this comes up here is that JIS mirrors the
entire ASCII set into its multibyte encoding -- including the comma.
So if we don't unify ASCII ?, with JIS ?,, you could have symbols that
have commas in them but those commas are syntactically non-commas. ;-)
