I guess you mean just for the metaclasses. C, S, and the assumptions metaclasses are the primary metaclasses, and the first and third we would like to remove. To translate S, you would just need to switch over to whatever kind of singletonization is possible in C++. The actual classes in SymPy are immutable and really shouldn't be changing after being constructed.
