Now, if the object on the far left was some kind of
accumulator/container, the
effect of sending something like three "add the number 3" would be
similar to chaining. But even if you mulitply the number 2 by 3, three
separate time, 2 * 3 still equals 6.
In fact, in order to get chaining with keyword messages, you apparently
need to define it, or especially adapt eg: containers to return ^self.
But as should be obvious, I'm not very familiar with Smalltalk. Some

I'm not sure what Simula did, but at least in Smalltalk this is how OOP have worked :-)

I'm not sure that's the best takeaway; consider:
