Description

All of the collections in the former collections crate use the front/back naming convention, but slice uses a first/last naming convention. I doubt that deprecating the former is a good idea at this rate, but it's worth talking about— should the methods first/last, first/last_mut, split_first/last be renamed to front/back, or should it go the other way?

Research direction

Start by comparing the front/back convention in the former collections crate with slice methods first/last, first/last_mut, and split_first/last. Done requires resolving which naming convention Rust should use and documenting that decision through the RFC process.
