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...
