in thread (Golf) Multiply polynomials

Nitpicking some more, if you want strict I can give you 84 characters:
sub p{ my@m=1;for my$p(@_){my@a;for my$i(0..@m){my$j;$a[$i+$j++]+=$_*$m[$i]fo +r@$p}@m=@a}\@m }
And note that I handle 0 or more polynomials correctly. (The empty product in math is "1".)

    This must be under 5.6 or the like; "for my$p" and "for my$i" lead to interpreter problems under 5.005_02 (Win32). Bug or feature change?

      Um, bug. I was too glib.

      But that makes getting a strict version with a count of 84 a point of honour, right? :-)

      sub p{ my@m=1;for my $p(@_){my@a;map{my$j=my$i=$_;$a[$j++]+=$_*$m[$i]for@$p}0 +..@m;@m=@a}\@m }
