> In Java 8, the Predicate class is suitable to be used for Constraints. And I think we should leverage the versatility of this on Ver 3.0
> The difference is that the Predicate.test() method is lacking the Annotation argument, which often used to pass arguments to the constraint. But we can equally easily inject the annotation instead.
> I think that that org.qi4j.api.constraint.Constraint class has no purpose, other than for compatibility reason, but I might be wrong.
