I'm torn... On the one hand, I see the logic in this. On the other hand, I suspect many developers will end up writing such a function anyway (regardless of whether it's a good idea), and it'd be nice if there was a standard spelling.
I realize this is not a convincing argument; I'm just thinking out loud a bit...
Maybe I'll start a "StdBadIdeasLib" project, for all the ideas that could be implemented straightforwardly on top of the existing stdlib, but get rejected because they're bad ideas... Come to think of it, that's probably a bad idea itself (at least it'd be a well-named library, though).
