CPython's cyclic garbage collector (was [Python-ideas] Automatic context managers)

I believe the reason something isn't already done to break cycles is
that the authors of the cyclic garbage collector considered the above
aphorism.  They rely on the author of the code with the cycles to
figure out how to break them.  All I was suggesting was that Python
could provide a hook where the programmer could codify his algorithm
for breaking cycles.
