I agree. That, and no need to rush new features, stabilize old ones and fix their bugs. I am still waiting for RFC0066[1] to be fixed. It is from 2014-05-04! Here is its GitHub Issue: https://github.com/rust-lang/rust/issues/15023. Backstory: I started writing a relatively simple Rust program many years ago when I ran into this issue. It was my first attempt at writing Rust, and I did not like the workaround.
