Thanks for the note.
In the current design draft the section
https://go.googlesource.com/proposal/+/refs/heads/master/design/go2draft-type-parameters.md#constraint-type-inference
describes a case where we need both a type list and a method. I don't
see an obvious way to implement that with your suggested syntax.
