A tip. Whenever possible go for the one-line looping constructs. The following two are equivalent logically:

for(A;B;C){} A;C while B;
however the second has 3 characters you may be able to drop. So use it. Even if it means using commas etc in C to get it to work, use it. (I am able to drop the 2 spaces.) A technicality, to be sure, but a significant one.

Also while the binding of and can make it better than &&, if you see it used that way, look for a way to move things around to get the && in somewhere and save a character. Watch:

sub f { $t=pop;$t=$$t{$c>0?l:r}while$c=$t&&$$t{d}cmp$_[0];$t }
Not something you would write from scratch, but there you have it...
