I'm very impressed. :-) I don't like the notation but I am very impressed indeed. A couple of niggles though. It looks like the results of the "Dog Kennel" tests are inconsistent. Id also like to see the results of

{
  my ($x,$y,$z);
  my $to_dump=capture(capture($x,$y,$z),$x,$y,$z);
}

Ill be checking this module out very soon indeed. ++ to you.
