That makes sense. In fact, the way I was using it until now it didn't
matter but I will have to keep a little more state for the new
functionality I'm developing, hence the question.

I'm a bit new to Smalltalk/Squeak/Magritte terminology and I'm not
sure what class extensions mean. May I bother you for a small example
and a pointer for more explanations?

That's what I thought but I was wondering about the tight coupling.
But as you mentioned, it's likely class extensions will fit what I
need--if and when I understand them. :-)
