in reply to An irrational coding choice found

I need a new approach to breaking me of this bad habit.
I bet that in the majority of your cases, it doesn't make any difference on whether you're using a hash or an array. Unless this access is 1) a bottleneck, 2) the current performance is unacceptable, and 3) changing it to an array makes the performance acceptable, then you've made the wrong choice.

Otherwise, it isn't worth fretting about.

    I concur; there is value to be had from learning *how* to get that last little squinch of performance out of a bit of code, but the actual doing-so should be saved for when you need it.

    The choice of an array-vs-hash for me frequently comes down to readability for myself and my teammates--someone else who isn't as skilled with Perl as I am will have to read this, so it needs to make sense. For the way we work, that usually means "hashes."
