Well, it can be done (and I've seen it done) with various hacks, but I agree it's not pretty, but it is at least slightly prettier than piles of asm. That being said, I saw you posted a more generic solution that looks like a real solution that can scale. I'll have a closer look at that. Thanks for working on it.
