I haven't tried out Rust for several months, but it's one of the languages I watch as something I might use someday. A recent discussion of compiler speed as a lower priority worries me somewhat, though. That's one of the priorities I feel Go gets right. Go gets other things wrong in my opinion, though. Hrmm.
Compiler speed on Rust is somewhat blamed on Hindley-Milner-ish type inference, by the way. They feel that's important.
