1. What are the rules for using __del__ besides: 'don't use it'. 2. What happens when I SystemExit? __del__ and gc are not invoked when I SystemExit and there's a circular reference - but why? The OS is going to reclaim the memory anyways so why be finicky about circular references - why can't we go ahead and call __dell_ and run gc?
3. import foo def __del__(self, foo=foo): foo.bar() What happens here to prevent a NameError? Apparently without the foo=foo a NameError can occur? But why? import foo creates a reference to the object anyways so it's refcount will be above 0 anyways till __del__ is called. 4. also, are method calls more efficient than function calls? -- https://mail.python.org/mailman/listinfo/python-list
