The biggest problem with the Rust compiler is not it's speed in compiling. It's that rustc from 3 months ago can't compile most Rust code written today. And don't tell me that cargo versioning fixes this, it doesn't. The very improvements we are celebrating here, which are very real and appreciated, are part of this problem. Rust is young and Rust changes very, very fast. I think it'll be a great language in a decade when it's no longer just used by bleeding edge types and has a target that stands still for more than a few months.
