D'oh, I see where I was going wrong, I was reading it as [3,2]
being 3x+2. Now I see ability to whack zeros with no problem :D
However, to nitpick, the 75 char solution (update above), isn't strict; you need to add 12 characters to strict-ify it. (my@m, for my $i, for my $p, my$j ), so to compare with the other solutions, at least mine being all strict, you're at 87.
update-fixed bad square brackets.
