Joachim has already conceded in earlier posting the existence of differences and different concepts.  Here is another such concession.  Since Smalltalk methods *are* coroutines, capable of fully handing off computations and controlling concurrency between them with substantial generality, aren't they therefor "different" from subroutines, even in Joachim's argot?
