> I haven't encountered a code base that uses non-default array indices, If you're referring to <parent>'s mention of Ada with arbitrary ranges of indices, that's less about thinking of them as array indices and more of "a range of indices that make sense for your domain". Thinking about your problem in your problem's space rather than "how would my computer think of this"; making the map more like the territory, as it were.
