I do this all the time. It's really not that bad. I can't claim that my functions are exhibit ideal style (especially in the grittier systems code), but I find that a numerical sequence has higher information per character than using more words to imbue more specific meaning.
For example, in erlctl I do this a bit when processing the command-line into my options proplist. Code here:
In that function, I can't imagine a better way to name Opts. I suppose I could have broken it into different functions and traversed them somehow, but I just don't see that as being any clearer.
