This is a compiler bug. This has no bearing on the language itself. Bugs happen, and they will be fixed, even this one.
It's a 10 year old bug which will eventually be fixed but may require changes to how Rust handles type variance.
Until you guys write an actual formal specification, the compiler is the language.
