Comment:
Ok guys, you did it, I have no way to write a new `__eq__` method in
`Poset` which is not "self is other" without getting an infinite loop.
If I want to actually compare the data of the posets (hasse diagram,
vertices), then comparing the data will raise a call to compare their
parents, and I'm gone for another loop.
Now what ?
