It turns out there is no real TODO here - things are working fine. If we are generating a wrapper for a method on a generic type that is actually the method on embedded type, then we should just just generate the normal embedded wrapper, which calls the wrapper for the real receiver type on that method. There is no need to do the generic path where we add in the dictionary argument. So, just updated that TODO comment with this explanation. Added a new test case embedded.go, which specifically tests various situations involving converting to empty and non-empty interfaces. issue44688.go already tests a bunch of these situations as well. Also made some other cleanups in reflect.go: - The shape test (that I had added) at the top of imethods is useless (never true), since it is always an interface type, so removed it. - Added usual helper function deref() to make code clearer in several places. - The shape test in methodWrapper() doesn't have to check HasShape() on each targ - it can just check HasShape() on the whole receiver. - The comment about disabling the tail call optimization for RegABI is no longer true. - Simplified code in several places by using the value of existing variable 'methodrcvr'.
