Cascading is something different -- it's for sending
multiple messages to the *same* receiver. It's not
dumb to have both.
I know what cascading is for. The issue is that with message cascading
+ the "yourself" message, you *never* need to chain on self (you can
just cascade and -- if you end up needing the instance to drop down at
the end of the cascade -- send `yourself`).
Chaining on self is completely redundant in smalltalk as the purpose
of this pattern is *also* to send a sequence of messages to the same
receiver (something message cascading already handles & guarantees).
Therefore defaulting method to self-chaining is very dumb and serves
no purpose whatsoever. It doesn't make the language easier to use,
less verbose or more practical. It just wastes return values.
