(rx-submatch-n 2 nil)) I think better would be to allow the existing subform `submatch' to support numbered groups, i.e. in addition to the current form `(submatch SEXP1 SEXP2 ...)' also support `(submatch N SEXP1 SEXP2 ...)' because the number is a parameter of normal groups. There are already subforms that support different number of integer arguments like `(repeat N SEXP)' and `(repeat N M SEXP)'. So the same could be done for `submatch' too. -- Juri Linkov http://www.jurta.org/emacs/
