It seems to me that the try() mechanism could easily be undone by gofmt. That is, if it does not work out it could be changed with low pain. This is a virtue. Maybe the lesson is lost on some, but Go 1.0 was incompatible with primordial Go and the Go team provided GoFix to mutate code. That was beautiful to me. Any new idea that seems promising but could be undone automatically if necessary is not risky.
