[ruby-core:106739] [Ruby master Feature#14394] Class.descendants

Issue #14394 has been updated by matz (Yukihiro Matsumoto).


`Module#descendants` has been proposed too in #9779.
In addition, upon the existence of newly introduced `Class#subclasses`, the need for `Class#descendants` is decreased.

Considering those facts, let up postpone introducing `Class#descendats` for 3.1.
I feel we need more discussion. Sorry for the last-minute change.

Matz.

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?
