I first had it coded as you suggested, but two thoughts occured to me:
  1. Keeping in inside an array would be faster to walk (foreach (@arr) has to be faster than doing 30 hash lookups).
  2. An order (and count) needed to be represented (for maintainence purposes) anyway, so why not just keep it in an array ref in the first place. I thought of the time stamp, but looking it up and testing for it would consume MUCH more time than a simple FILO algo. Remember, I'm trying my damnest to minimize the work the cache has to do.
Heck, I even tried blessing an array ref instead of a hash hoping I could make a class from that; but of course that didn't work :)

Now, here is an addition question. Is

$class->method();

any slower than
Class::method();

[download]
? And by "slower", I mean technically, not noticably :)

TIA!
