I'm surprised by the comparison to perl6. Rust is moving very quickly now, but they clearly have a cutoff in sight, and their explicit goal is a stable language spec and standard library for 1.0. They are also building on LLVM, which gives them a fairly solid base; in contrast to perl6 that was trying to make a multi-language VM while reinventing the language.
