Wow, thanks for the link to the Summer of Code, that looks like fun! (I know I'll be thinking about my proposal all day at work : ). I don't have my TODO list with me, I will try to post it later today. I have been working and thinking about improvements to the Parrot/IMCC optimizer for a while now. Implementing SSA is definitely at the top of my list, because it simplifies a lot of optimizations and makes some others possible. The biggest challenge is to graft such a big change onto a working system, with small changes at a time. The reference to LLVM is interesting, since it has similar goals to Parrot, but is research-oriented. I bet there are some good techniques that could be learned (and borrowed : ) from LLVM. -Curtis Rawls
