Andrew was asking about usage data in another reply to this thread,
have you (all?) had much trouble allowing these characters in
identifiers?  Has it caused serious confusion anywhere?

I said in another message I'd hoped these would not be allowed at the
beginning of an identifier (my preference, though).
