Hi Marcel,


#cannotReturn: is put onto the stack of the process being executed/simulated. #send:to:with: is part of the simulation protocol. Analogously, #resume:through: will appear on the executed process stack whereas #return:from: is used by the simulator as stated in the comment. :-) I think these methods are already arranged in two different protocols, which are "controlling" for the execution perspective and "instruction decoding" for the simulation perspective.


Best,

Christoph

Hi all!

Take a look at this:

[cid:f1a64b9d-78f4-4480-bacf-75cff8b29d45]

When would a context use #send:to:with: and when just directly send it?

self send: #cannotReturn: to: self with: {value}.
self cannotReturn: value.

self send: #cannotReturn:to: to: self with: {value. self}.
self cannotReturn: value to: self.

There are other examples. See:
Context >> #jump:if:
Context >> #return:from:

Best,
Marcel
