Howdie, love your work, and just stumbled across this which also looks awesome :)

I use prettier with JavaScript, and cargo fmt with Rust, and they both automatically (and consistently) break up long lines

Example func:

func somethingTooLong(ctx context.Context, longArgument string, anotherOne func(time.Duration) bool) (int, error) {
	// foo
}

func somethingTooLong(
	ctx context.Context,
	longArgument string,
	anotherOne func(time.Duration) bool
) (int, error) {
	// foo
}

gofmt doesn't do this, but it also doesn't undo it where I've done this manually, so at least this particular example is gofmt-compatible

That's also a good point. Splitting one line into two, when two lines adds ambiguity, is not good. The example I shared would need another extra newline to become non-ambiguous again. I worry that it might be tricky to determine "will the new format look ambiguous", though.

Though I still think the line on its own should be left alone, even if the ambiguity wasn't an issue.
