As far as I can tell, the latest proposal draft forbids type parameterized methods. One must admit the type parameter to the receiver or define a type parameterized function. I am making no claims about your broader point, only clarifying that your example is not permitted by the proposal draft. See https://go.googlesource.com/proposal/+/4a54a00950b56dd0096482d0edae46969d7432a6/design/go2draft-contracts.md#methods-may-not-take-additional-type-arguments https://go.googlesource.com/proposal/+/4a54a00950b56dd009648...
