I think it's perceptive to split the guts of the phrases on [ ]and[ ], but it's really important in my case that the leftovers are only digits. While I could throw grep { /^\d+$/ } in front of the split, I'd lose visibility to any non-digit stuff that was (mistakenly) there in the process of following through with the replace side of the (s)ubstitute operator. In other words, I'd rather leave everything alone if there's anything "non-digit" besides the and splitters in there. BTW, I like the single-quotes for delimiting the split regex.
