I am not sure where we will get the speed improvement but if it's by limiting the amount of classes we scan manually, the we probably need: - Getting classes/method/ctrs annotated with meta annotations is useful. - Getting intersections of annotated classes too: get all class with @Named and @Startup, could be useful too (not entirely sure but I can see a couple of use cases) - Getting a class hierarchy: its often that you need to build a class hierarchy based on a given class, might be useful as a service?
