As I’ve been asked, I’ll clarify a bit more. When I said it worked before I was actually wrong because I had forgotten to remove some alternative cleanup code (the alternative works but it’s like using a cannon to kill a fly).
This is part of the interpreter for Live Robot Programming that Miguel and I are working on. As part of that we need a data structure that holds scopes, for variables but also for other things. It turns out that for the variables part we can map rather nicely to classes, which gives us a bunch of advantages. So for each scope I generate a class. The scope keeps that class in a ‘vars’ instance variable (there are never any instances of these classes BTW). When the scope is garbage collected I want to remove the class from the system. So I put #finalize in the scope with the idea to remove the class, but it turns out that ‘vars’ is always nil. So in the end it did not work out ... > On Jan 15, 2015, at 15:10, Henrik Johansen <henrik.s.johan...@veloxit.no> > wrote: > > Removing a class you're an instance of might be a bit fishy as well.
