This document:


which I wrote three years ago has some code to handle optional _ and ^
suffixes. I probably don't have the time to adapt it to this situation, but
this means that it is theoretically possible.

BTW, I uploaded an updated version of this document (on stretchable big
operators) to my old website, which no longer exists (In the future, I
won't trust free webhosts). If anybody actually downloaded it, would you
please send it my way?
