Comment(by vbraun):
I don't understand the GiNaC documentation that you referred to
(http://www.ginac.de/reference/structGiNaC_1_1expair__rest__is__less.html).
They state it is not a SWO, and their example is that neither 3*x<2*x nor
2*x<3*x. But thats perfectly fine in a SWO, you can have incomparable
elements. The only constraint on incomparable elements is transitivity,
that is, if A and B are incomparable and B and C are incomparable then A
and C are also incomparable. Do you understand why its not a SWO?
