Issue #14394 has been updated by Eregon (Benoit Daloze).


Could that work with just the Class#inherited hook?
What's the advantage of asking all subclasses/descendents of a class instead?

Feature #14394: Class.descendants

----------------------------------------
There have been numerous implementations of the method Class.descendants by various gems. However, I can't help but think that this ability should be included in the Ruby language itself. Especially since Ruby already offers the counterpart method Class.ancestors.

Would it possible to add a `descendants` class method?
