Thanks; that reproduced the bug.

I'm not a Scheme expert by any means (I haven't used it in decades), but
I think your patch is at least more correct than the old regexp, which
required that all symbols start with a word-constituent character.  That
has to be wrong -- surely ".foo" is perfectly fine as a symbol in
Scheme, too?

So I've applied your patch to Emacs 28.
