Review comment:
The goal of this (which, yes, should have been better documented) is to
quickly be able to prohibit fusion. But the reason we defined our own union was
so that memory didn't grow as O(n^2) in the common case because many stages
were able to share this set (rather than have their own copy). These changes
seem to break that.
Also, could you clarify why this was made into a dict?
