in thread global regex returning a list of arrays?

yeah I knew this trick with the index-array, thx,!

But it's not really comfortable to need to substr... :(

    BTW: couldn't find an array holding the values of $1,$2,... in the perldocs !?!

    Probably not much help in this particular case (and you still need to loop to capture), but 5.10 offers the %+ and %- predefined hashes for named captures (see perlvar) in place of an array of all capture groups: 

    >perl -wMstrict -le
"my $s = '12ab34cd56ef78';
 my @pairs;
 push @pairs, [ $+{A}, $+{B} ]
   while $s =~ m{ (?<A>[[:alpha:]]) (?<B>[[:alpha:]]) }xmsg;
 use Data::Dumper;
 print Dumper \@pairs;
"
$VAR1 = [
          [
            'a',
            'b'
          ],
          [
            'c',
            'd'
          ],
          [
            'e',
            'f'
          ]
        ];

      actually it's getting better now! :D

      ....it's possible to take the values of the hash!

       push @pairs, [ values %+ ] while $s =~ m{ (?<A>[[:alpha:]]) (?*[[:alpha:]]) }xmsg;

      unfortunately the hash is not set when the groupings are not named ... :(

      Cheers Rolf
