I'm currently doing something like: 
$counts{$n{'Rep'}}{$n{'Item'}} += $n{'Qty'};

This is fine if I always sort the data this way, but what if I decide I want to use a 3-level hash without hard-coding the data assignment? How do I efficiently take an array of keys: 
@keys = ('Rep','Item','Whatever');

And translate it into: 
$counts{$n{'Rep'}}{$n{'Item'}}{$n{'Whatever'}} += $n{'Qty'};

It doesn't have to be neat, or the fastest code on the planet, but efficiency is somewhat of a concern. I suppose I could use eval (since this is an admin script and placed safely out of reach of hackers), but I'm interested in seeing if there are other ways.
