I'm not sure about the specific nuances that the terms cover -- I've so 
far only implemented Multi Method Dispatch and it supports arbitrary 
predicates as well as typical Class- and Instance-based dispatching.

But even when being able to specify arbitrary lambdas as dispatching 
scorers it is still not trivial to use a TestSuite as a contract check. 
Not sure if test/unit allows for an easy way of doing that...
