Description

There's this code in reflect/type.go:

                                    if ift.nameOff(m.name).pkgPath() != "" {
                                            // TODO(sbinet)
                                            panic("reflect: embedded interface with unexported method(s) not implemented")
                                    }

See also #5748.
