The language stability of Rust has already reached somewhere similar to Python 2.0: no core features would be removed, so some syntactic changes can occur before 1.0 but that wouldn't invalidate any effort to learn the language before 1.0. Would you say that Python 2.0 is not very useful because it is constantly changing and some features even get removed (albeit quite slowly)?
