in reply to Regular Expressions: Call for Examples
Can I throw a problem at you that I never took the time to think
out and that may add some salt to your book? In perl5, it is impossible to get at capture in an embedded
regular expression:
my $qr = qr|whatever(somecapture_re)whatever|; my ($captured) = m/$qr/; # does not work
A few week ago, I looked at your draft (forgot the URL). It looks promising. My problem is: find an API to stash away that information and get it back. Probably, it will not very pretty but there no way to "modularize" regexen in perl5. I mean by that, to build interesting regexen from simpler ones.
I once looked at your draft (forgot the URL), it seemed pretty interesting.
