> - Process has a badly named instance variable - "myList".

I suppose you mean because of the "my" prefix?

I read an article once about private variables/methods in Smalltalk. 
The author suggested, for variables/methods which you want to emphasize
their privateness, you name them mySomething.

He argued besides emphasizing the privateness it even has a punitive
property; any outside callers must endure strange-looking code, as in,
someProcess myList.

I can't say I've practiced it too much, I find the 'private' method
category sufficient documentation..
