yeah no. you need an acyclic structure to maybe guarantee this, in CPython. other Python implementations are more normal in that you shouldn't rely on finalizers at all.

I love Python, but the sheer number of caveats and warnings for __del__ makes me question if this person has ever read the docs [0]. My favorite WTF:

> It is possible (though not recommended!) for the __del__() method to postpone destruction of the instance by creating a new reference to it. This is called object resurrection.

>>sgarla+5d
How does this relate to the claim of the parent comment that cyclic structures are never freed in python (which is false, btw)?

>>guappa+kf
this is not what I claim, BTW.
