Not sure about. Waldemar's examples can bite plain old expression-statement refactoring too. Is this really a fatal flaw of paren-free, or more a problem with C-family expression-statement syntax?

If ASI is the culprit to focus on, I can work harder on ASI in relation to paren-free. I do not want to hack on paren-free by itself. It's quite simple and not in need of "patching".
