That's probably a good idea; the optional argument could be either an alist or a symbol like 'short or 'verbose.

Good defaults are just as important. I thought that one-or-more would be more descriptive than + or 1+ for those not familiar with the rx notation, but perhaps this was a mistake.

Which would you prefer as default symbol from each of these sets?

 one-or-more 1+ +
 zero-or-more 0+ *
 zero-or-one optional opt ?
