Hello !
We already have a `Graph.disjoint_union` that accepts this kind of
parameter. If you want to have a similar feature at `Poset` level I
suggest that you only expose this function. The code would just be :
{{{
return Poset(self.hasse_diagram().disjoint_union(other.hasse_diagram()))
}}}
Then, if you want to have more ways to tune the result through the points'
name, the best would be to change the Graph function itself, which would
consequently give the same feature to the Poset function.
