I find Odersky's comments on Swift very apt. I think both Scala and Swift are aimed at being mergers between FP and existing OO systems and both of them feel a little warty for the effort.

I think it's going to be a much larger and harder project than either Scala or Swift will benefit from, but I'm really glad that they're exploring the design space.
