Subject: [ruby-core:55048] [ruby-trunk - Feature #8422][Feedback] add Enumerable#reverse_sort and Enumerable#reverse_sort_by


Issue #8422 has been updated by matz (Yukihiro Matsumoto).

Status changed from Open to Feedback

It can be done by a.sort{|a,b| b<=>a}.  Do we really need to define new methods?

they are better when you want descending order,
  enum.sort.reverse
does work too, but it is to slow because it needs to build that result array twice

they both can be defined just like #sort and #sort_by but negates the result of the compare block
