I don't think that's what's meant. It means to write `func (Receiver) Method()` rather than `func (r Receiver) Method()` when you don't use `r`. Sometimes you need this to implement an interface like `error` or `Stringer` and you just don't need instance data.

(I'm no Go apologist but I think "receiver" is a great term. It's clear, it's applies to other languages and paradigms, and it doesn't really have an alternative that I'm aware of.)
