In Go, however, go fmt will remove the unnecessary parentheses. I was very annoyed at first, when I saw this, but I got used to it.

Does it generally do this in expressions, based on operator precedence, or is it limited to the outer parentheses on selected statements?

I am not an expert, but I think it only removes the outermost ones. The major task of the tools is indentation and placement of curly braces.
