Thanks for that. That would certainly work to a degree, much better than =
my current alternative, but it nullifies the usefulness of named =
captures. For example, I can't call

$ md1[:first]

and get back all the matches for the (?<first> ) grouping, which would =
be phenomenally useful, because scan returns arrays of strings and not =
matchdata.
