Yes, rust-next works, but I was imagining renaming the current rust to something like default-rust-build, then defining a new ‘rust’ which will be continuously updated to the latest version of rust. 

I think a user centric design would name the latest rust as just ‘rust’, while letting the package-manager implementation detail have the longer name.

Using your proposal, how do you deal with

guix install rust rust-foobar

? Do you expect that rust-foobar is built using the latest Rust or the
internal Rust?

Well, from my point of view, what you would like is that the symbol
’rust-1.65’ would be named “rust-next”. It is the current way for
several versions; see emacs vs emacs-next.

See https://issues.guix.gnu.org/62643

I propose to close this report once #62643 is merged.
