Replying to [comment:3 ncohen]:
> Also: the code of `Poset.level_sets` is a call to `.hasse_diagram()`, so
perhaps you should call that function instead.
Hmm, actually it seems that only `reverse()` is needed. There is no need
at all to calculate full dual with element labels. Got to think about this
tomorrow.
