This places Any also at the *bottom* of the class tree, if you can call it that. (And hence it is more a graph than a tree -- but if you remove Any, what's left is a tree again.)
I may be misunderstanding the context, but since Python has multiple inheritance, the "class tree" was already a graph even without Any.

Thanks, that was a simple "thinko". I meant that without Any (and perhaps barring some other pathological cases due to Python's extreme malleability) it's a DAG, but with Any it has a cycle. I've also updated the Quip doc to speak of "class graph".
