Actually, revisiting http://stackoverflow.com/questions/1661197/valid-characters-for-javascript-variable-names I see I need to have two regexes because I do need to special case the first character. I had forgotten that certain unicode groups are only valid as second+ char. I thought (/had remembered) the limitation only applied to numbers. Interestingly enough, I stumbled upon it because I was editing in 0x200d which rang too familiar a bell for me. That's when it dawned to me. Ok, I'll fix this later.
