The match for lives within the scope of the capture group, which you get via $m1[0].

As the group is quantified with *, the results will again be a list, ie you need another indexing operation to get at a match object, eg $m1[0][0] for the first one.

The named capture can then be accessed by name, eg $m1[0][0]. This will already contain the match result of the appropriate branch of the protoregex.

If you want the whole list of matches instead of a specific one, you can use >> or map, eg $m1[0]>>..
