Even if we were to use UnaryPredicate or the Predicate from collections, we would be stuck with an ugly cast of the argument to Context (or some subclass of it) in every single command. It's also not clear how we could accomodate the concepts of Chain and Catalog that are integral to my vision of what we need in the support library. I'm currently -1 on trying to incorporate or merge with commons-functor, at least until we settle on what functionality we expect the low level chain of responsibility package to provide.
