I am saying that there are examples where it is desirable to move one of the arguments that this form of refactoring forces you to put in the constructor so it instead becomes the argument of the first send.
I'm having trouble seeing circumstances in which you would need to do that. Can you provide an example in the form of
(a) a piece of unfactored code
(b) a desired refactoring
(c) an explanation of why the desired refactoring can't conveniently be done using an unprimed generator and plain yield-from.
