In reading both your comments, I kept thinking about Smalltalk's Browser and Method Finder functionalities. In Hay's book, he talks about modeling not just Object Classes, but how you can go about modeling ObjectClass classes (the metadata). In Smalltalk, this metadata is automatically available via the Browser. In reviewing the CQL Tutorial, the Typesides' "java_functions" specification section made me think of the Method Finder (wherein you could provide an input value and the expected output value and methods that satisfied the transformation would be shown). I'm not sure if in CQL you'd be able to search for a function that satisfied criteria, but that may beyond the scope of what that system is trying to provide. In any case, interesting threads of thought to be followed and explored.
