For this to work we would need a unique ID in the RTTI, right? I don't think that exists so unless it does we need to do equality comparisons for each case.
The class type already is a unique "ID" for each class type when doing an equal comparison. You can essentially take the address of the VMT as the constant values that the loaded value is compared against.
