I withdraw that last remark. It was uncalled for. I was trying to
posit that there is nothing special about the English alphabet, and
that all Unicode letters are acceptable as identifier names, but I
didn't express that very well, so if I caused any offense, I
apologise.

I still don't see how the rule generalises to N elements though, and
so my question about the rule is still open.
