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.
