This program is valid, but ICEs with the nounified frontend: https://go.dev/play/p/54ohNsbev55

It appears to be a bad interaction between method expressions, receiver parameters of derived type, and method embedding.

It currently works with GOEXPERIMENT=unified. Marking for Go 1.20, because I expect enabling unified IR by default is how we'll fix this issue.
