It's a helpful link, thank you. I think I need to play with toolchain more. Last time I checked I think there was some corner case that was not covered but I could be wrong.

With `brew install go`

and

module github.com/anttiharju/vmatch

go 1.21.0

toolchain go1.21.1

I still get a binary that claims to be built with the latest version of Go instead of 1.21.1 or .0

vmatch has version 0.1.6+dirty built with go1.24.3 from 83c9aa83 on 2025-05-25T18:43:30Z

I think this is a problem for me. Go 1.22 did a breaking change with the for loops for example https://go.dev/blog/loopvar-preview.

I see that I can change it with a command like `go env -w GOTOOLCHAIN=go1.21.1+auto` but then again I'm doing something I don't want, managing the version.

Perhaps I'm missing some config.
