I got it; see my answer to Juan. I guess I'm just programming in bad 
style: I do indeed consider that Object is part of my packages (or, more 
accurately, that Object is not a forbidden place for my package to go in).

The pleasure I have in programming Squeak comes largely from the fact 
that I can dig code all other the place and tweak whatever class I want. 
I need first to understand what a class is, what it does, then I have to 
respect the way it is used in the image, but then, when I'm confident 
enough that I am not behaving like a rude person, I feel free to add my 
own code to it. That's my style.
