A fairly major blocker for some work I am doing is the ability to extend type declarations: declare B extends A .. end Such that the patterns take into account the polymorphism (which I think they already do). Is there any plans for this type of feature and/or is there a way of intercepting the resulting Java definition arising from the syntax in order to programmatically set this?
