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.
