I was thinking of taking the sideways route - instrument the ')' part of a '(...)' group so that the contents of @+ is copied elsewhere for safekeeping. Any time that I'm interested in knowing which newly closed group was just passed I'd look for the index of the newly defined value in @+.

So after (a)? $+[1] and $+[2] are undefined. After (b) $+[1] is still undefined but $+[2] is defined (and equal to 2). So... if I can know which @+ entry was just created is that sufficient or will that break as well?
