PLT Gets JIT

According to this message to the PLT Scheme mailing list, PLT Scheme just got a JIT compiler. It only works on the non-3m (i.e. Boehm conservative collector) version of PLT Scheme, but it seems to provide some speedups. Subsequent messages suggest that they're working on a "proper" JIT compiler targeting LLVM which should provide even more speed. Very nice!

Update: I've been using the JIT version for the last day (my normal preference is for the 3m version), and it's really nice! I see speedup near a factor of 2 for much of my code (which is pretty loop-heavy, so maybe that helps get the extra speedups), and the whole experience of using DrScheme feels much more snappy!
