04:56 AM Ruby Revision de56b5e2 (git): Make Module#descendants follow the ancestors of the current box

The subclasses lists are kept only in the prime classext and thus shared
by all boxes, so a module included into a builtin class in a box was
reported as a descendant from other boxes, where the include is not in
the ancestors of the cla... shugo (Shugo Maeda)

02:24 AM Ruby Feature #14394 (Closed): Class.descendants

Module#descendants was added instead of Class#descendants, so I'm closing this issue.

01:29 PM Ruby Feature #22213: Allow no-argument and chained calls of Proc#refined

I forgot to mention the change to Proc#==: it now compares not only the underlying iseq but also the sequence of modules passed to Proc#refined.

Since `prc.refined(*ms).refined(*ns)` is behaviorally equivalent to

equivalent Procs. A Proc that is never call... shugo (Shugo Maeda)
