OK for me. Then it would be like `.disjoint_union(other,
labels=’integers’)`. Current behaviour would be maintained, so there is no
need for a deprecation. Should `disjoint_union` have an option to get
really direct union (and raise an exception it graphs have common
vertices)? If not, I will add an example like we now have for disjoint
union of posets.
And then there is the naming thing.
But first I will wait for three days to see if there will be opinions
against this.
