Okay, I cannot resist. This is the product of not enough sleep and I warn all who continue. Given we have used merlyn's suggestion for a hash of arrays ( I was actually thinking of an array of ararys, but why not a hash? ), what if we did something like this
sub compare { my %data = @_; my @lengths = sort { $a <=> $b } map { scalar@{$data{$_}} } keys %da +ta; return $lengths[0] == $lengths[-1]; }
Basically, if we sort the lengths and the last element is equal to the first element, then everything else inbetween must be equal.

This has likely no value - it really isn't clearer nor does it likely save any cycles. I just thought it was fun and have not had enough sleep.

UPDATE: did I mention not enough sleep? Fixed a typo
