But what about latex-ams-symbol% and latex-stmary-symbol% ?  And how
would we reference these rules ? (drd-ref ...) ?  I guess I don't know
enough about DRDs.

OK, I will re-work the patch with (drd-group ...)

Exactly. I was thinking about whether to turn the RHS into a list, or
whether to only turn it into a list when it's necessary, and then do

(let ((drdval (drd-ref %latex-needs something)))
     (if (list? drdval) ...
         ...))

Unfortunately, this may cause many of these (if (list? drdval) ... )
lines to crop up all over the file, so I decided it would be more
consistent, and more reflective of the workings of TeXmacs to have a RHS
that is a list.

I suppose I could make one ... heck, this could be a project in itself.

As the Hungarians would say: "This is the future's music." - the near
future, though :o)
