I don't use it in MAReports, but I define queries based on the descriptions for instances yet unknown, so the use case is similar. Currently what I did is an approach similar to how Dolphin Smalltalk handles its "Aspects", e.g. Model>>mementoClass ^self class mementoClassOfInstances Model class>>mementoClassOfInstances ^MACheckedMemento And this can be done for almost everything, incluiding building the description container, ask the instance first, and then the class. Also, I like the pragmas, but only for "tagging" the description methods, I prefer lookup and builds based on simple message sends. Regards, Esteban A. Maringolo
