Replying to [comment:32 ncohen]:
> You seem to say that implementing this function would have you implement
a helper function, which you do not think would be user-friendly enough to
deserve being public. Could you tell me what this function would do? I do
not see what you have in mind. Surely you are not talking of the
`ordinal_sum_decomposition` itself, as you made it publicly available in
this branch?
It is "public", but in "private" class. Doc for Hasse diagram says "This
should not be called directly, use Poset instead - -". (It should say it
more clearly, but that's another thing.)
