module Crystal::SubclassObservable

Overview

Temporary type to recompute calls when a subclass is added to a type hierarchy. This shouldn't be needed, because the type hierarchy is now computed in a first pass, but for generic types, instantiations are considered as kind of subclasses, and calls must be recomputed to take them into account (but this should change in the future).
