Dang! I thought I had read the docs ;)

Seems very useful. I actually need to know all the matches, because
which one gets selected depends on the current priorities (ordering)
in the parser, and cannot be fixed for the scanner. (I could put the
patterns in the or-group in reverse prioritized order, but that would
have to be fixed...)

Thanks for the tip, anyway.
