I didn't test yet but I think what you're saying is that VMT writer would need to have generated this address in advance of doing tcasenode.pass_1, which could presumably get this address in some integer form. Is that basically what you're thinking is possible?

If it's a big problem I guess the question is if the if blocks are really that bad compared to alternative ( I would need to basically redo the entire thing also).
