Issue #6373 has been updated by marcandre (Marc-Andre Lafortune). File self.pdf added Slide attached. I hope to win the prize for simplest slide too. ---------------------------------------- Feature #6373: public #self https://bugs.ruby-lang.org/issues/6373#change-41440 Author: trans (Thomas Sawyer) Status: Feedback Priority: Normal Assignee: matz (Yukihiro Matsumoto) Category: core Target version: next minor =begin This was recently suggested to me as an extension: class Object # An identity method that provides access to an object's 'self'. # # Example: # [1,2,3,4,5,1,2,2,3].group_by(&:identity) # #=> {1=>[1, 1], 2=>[2, 2, 2], 3=>[3, 3], 4=>[4], 5=>[5]} # def identity self end end First, is such a method commonly useful enough to warrant existence? Second, it makes me wonder if #self should be a public method in general. =end -- http://bugs.ruby-lang.org/
