Relatively simple change to avoid headaches down the road.
If we have two ordered sets
Set(A, B)andSet(B, C)then a replacement of
AwithCwill allow two different set instructions that represent the same logical set (Set(C, B)andSet(B, C))This change makes sure that any uses of an
instin a set will cause that set to be created again (which will use the same stable global ordering)
