    I continue to be astounded at how much thought and care is put into Rust’s evolution. Great job, Rust team.

      Starting in Rust 2021, closures will only capture the fields that they use

      This fixes my biggest pain point really. Very nice!

        The 2021 Edition makes me especially happy because of how utterly boring it is. The changes are simply to take out jagged edges in the language as-is, but otherwise nothing new or big is being added (unlike the previous 2018 Edition with async/await).

        It seems like the future of Rust is really just smoothing out the edges, and the editions are a brilliant way of doing that, since we aren’t stuck with them indefinitely (or forced through a python 2/3 scenario).

          Note: the official position of Rust project is that Rust is stuck with all Rust editions released indefinitely.
