Do you mean the equality predicates, like ==/2 or =:=/2 etc, or do you mean unification? I dont' really think of unification as a constraint but, I don't know, maybe you have a point.

Yes I was talking about unification. When you can expand what unification means and program how it works, you have a real constraint system.
