Does operator= return a CSimpleStringT&? If so, Argument[*0] should propagate to ReturnValue[*] as well.

Indeed it does: https://learn.microsoft.com/en-us/cpp/atl-mfc-shared/reference/csimplestringt-class?view=msvc-170#operator_eq. Turns out I actually forgot that flow in a bunch of other models. I've included all of those in e777377. Thanks!

Note that I also fixed another MaD bug: we didn't handle varargs. This has been fixed in c5bb907
