That's a very good point, although I think I'd change the implementation a
little:

in pushSelf

myReturn &= { {} }


in WndProc/SubProc

object retval
...

if atom(myReturn[length(myReturn)]) then
        return popSelf()
end if
...

There are some other changes that would have to me made, of course, but all
this would be hidden from the user, anyway.
