Anything you like, I just made it up. That's the point: if a, b, etc have
overloaded the operators, they could mean anything. The idea I vaguely had
was that they constructed a graph, using => and <= as "arrows" so that the
above would be equivalent to the graph:
a -> b -> c <- d <- e
(a to b, b to c; e to d, d also to c)
