In case someone close to managing the QA rules is interested... on discord it was suggested that this form of cascading might be a trap for newcomers.

I've never seen similar in practice, so it might make a good QA rule. It currently raises "Sends unknown message to global" but I'd guess a more specific message that actually mentions "cascading" could be possible.

I was the one who brought it up on Discord, being it seems the forever newbie with Pharo... It's worse if you have a class-side method. The error is "Instance of X class did not understand #foo", which is evil to newbies because an "instance of [a] class" seems like it should be an object, and I *did* have a message of type "foo" defined.
