Hum? That's the purpose of the PEP 442 which is implemented in Python 3.4.

As I wrote, it's not enough to fix all issues.

Usually, I see an explicit call to gc.collect() as a workaround to a
deeper issue. I prefer to modify my program to run smoothly without
explict garbage collection.

That's why I would prefer to avoid creating reference cycles from the beginning.
