    Just like or is almost only be useful in structures of the form

    func arg or stmt;

    err would almost only be useful in structures of the form

    func arg err stmt;

    Simply replacing err with // would be wrong, but appropriate use of parens will do the trick:

    func(arg) // stmt;
    (func arg) // stmt;
    if (not defined func arg) { stmt; }

    etc.
