Add me to the list, because I'm writting the jit optimizer and ran into the same problem, we must add some metadata otherwise I will end up hard-coding all the information deep into the optimizer and that is a Bad Thing (tm). I don't know if this is the best way to solve this but I rather like it. Daniel Grunblatt.
