ordering(+Spec) is det: Specify the preferred variable ordering of answer constraints. A variable that comes first in Spec is the one the answer constraint defines, i.e. the one on its left hand side. Spec is either a list of variables or a term A<B or A>B. As ordering/1 interns variables the solver does not know yet, it may be stated before or after the constraints it talks about.
