             : 		if (tmp[0] != '_' && !isupper(tmp[0])) {
             : 			return 0;

Au contraire, that *has* been the longstanding precedent, and if users are truly free to do whatever now, that would be a change. Administrators and users trying to do it 'correctly' avoid uppercase variable names, whether that's codified or not.

However, as I pointed out, with registration, we can be more or less sure about the existence of conflicts though, so warnings about this may not really be necessary anymore as it is.
