Indeed, the problem is largely go fmt, I already raised this, but no one
picked up on it:
I use this one-liner:
v := a; if t { v = b }
This is not compatible with go fmt, but that tool's effects are
undocumented (see issue 18790 <https://github.com/golang/go/issues/18790> which
was declined), and it has no switches to disable/enable features. A
syntax-aware sed is a good idea, but sadly go fmt destroys useful
constructs. Other examples:
err := fn()
if err != nil { return err }
switch v {
case 1: pkg.one()
case 2: pkg.two()
case 3: pkg.thrice()
}
