I think unladen swallow is going to be a boon to Python and dynamic languages in general. The additional work the unladen swallow team has had to do to get LLVM into a position where it could support a dynamic language has slowed them down, but I'm confident that the effort will end up producing substantial speed boosts while also leaving behind an awesome general purpose VM in LLVM for other people to build on. It's not there yet, but it will be.
