Comment (by ncohen):
> Without copying code?
I do not understand this sentence.
What I meant is that your method could be a Poset method, which would
access `self._hasse_diagram` directly.
> Then ordinal decomposition function in `posets.py` should return
`HasseDiagram`, which sounds odd.
Why do you insist on having it return a Hasse Diagram? If you want the
decomposition feature without having to build posets, then you could have
a 'as_posets=True` optional argument in the Poset method, which would
either return a list of posets or return a partition of the elements.
