Re^2: How to use \l and \u in regex mathing patterns?

What an ugly hack.

If someone asks "How do I X with Y?", and you recognise that Y is a particularly bad way to accomplish X, then you are supposed to answer with the better way Z. If taking the question at face value, at least mention the caveats of Y.

I don't think it was a hack, ugly or otherwise. I think it was intended, and succeeds, as an example of the actual way interpolation control operators can work in a regex, which was the context of the original – albeit misguided, since pat_mc thought of them as character classes – question. (Although I must admit that, had I given the example myself, I might have mentioned that those operators are rarely used in that particular way.)	[reply]
