I'll do a gist. Before that, I note an interesting notation: **5 to control
the number of repeats.
What about suppporting these additional quantifiers (which are unambiguous
with with ** AFAIK):
**n
**{n}
**{n,}
**{n,m}
Right now, either I'd write card five times, either Id do a lexeme or G1
action on card* and croak if != 5 -;
Thanks / JD.
