Methods with unused receivers can be a symptom of unfinished refactoring or a bug. To keep the same method signature, omit the receiver name or '_' as it is unused.

Bad practice

func (f *Unix) Name() string {
    return "unix"
}

func (_ *Unix) Name() string {
    return "unix"
}

Recommended

func (*Unix) Name() string {
    return "unix"
}
