If #<=> is defined I would do the same, but that is not necessarily
the case. ">" might implement something
where ! ( !(a>b) -> b>a)  as e.g. superset, subset relationships. If
you are against such redefinitions, please read the example as
follows:

if a_set.any.superset?( b_set.all ) then

I wanted to make it clear that Junctions can be combined and thus
become a more powerful abstraction over relations.
Cheers

If you want to build a ship, don’t herd people together to collect
wood and don’t assign them tasks and work, but rather teach them to
long for the endless immensity of the sea.
