go/types, types2: spurious compile error when embedding a parameterized type in a struct #44688
Description
This program (https://go2goplay.golang.org/p/rF1kHzbn4Fc):
type A[T any] struct{}
func (*A[T]) f(T) {}
type B[T any] struct{ A[T] }
func main() {
var b B[string]
b.A.f("") // ok
b.f("") // compile error: type *B[string] of b does not match *A[K] (cannot infer T)
}
causes go2go to emit this spurious-looking error:
prog.go2:12:2: type *B[string] of b does not match *A[T] (cannot infer T)
