Hi
It took me more than hours to find the following for a #:grammar clause in
defform:
[ne-arglist arg (code:line ne-arglist @#,(litchar ",") arg)]
in order to produce
ne-arglist = arg
| ne-arglist , arg
It is abracadabra for me, but it works. I found it by trial and many errors.
It seems like unquote-syntax, but I don't see a quasiquote-syntax.
Surely I ought to read more docs on scribble, but where?
Thanks, Jos Koot

You can use `code:line` to group terms without parentheses:
(code:line addition + term)
