@b0rk I tried that (I think) and somehow it didn't work. I did git checkout -b go1.22.0 because I wanted to create a branch too. But there's a way to get your local git tied to a tag (remote branch?) so that your work is relative to that (but I don't know what that was). All of this was in the service of trying to reproduce a bug report whose ultimate cause was the bug reporter accidentally editing a file in the Go standard library (on a fast train with slow wifi).
