It's never going to be a class; it was supposed to be a module like in Ruby language, which is then mixed in certain classes that define _each to get enumerable goodness. But with prototypal inheritance in JavaScript that is simply impossible. A prototype chain is one-dimensional - each object can only inherit from one prototype. So if an object is already an instance of Hash (for example), it cannot have dynamic inheritance from Enumerable module. We can only copy enumerable functions to it. When new functions get added to Enumerable, they have to be synced manually with target classes. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Prototype: Core" group.
