[ruby-core:46867] [ruby-trunk - Feature #6373] public #self

From: "citizen428 (Michael Kohl)" <citizen428@...>
Date: 2012-07-29 18:42:11 UTC
List: ruby-core #46867
Issue #6373 has been updated by citizen428 (Michael Kohl).


FWIW, I'm the one who suggested this method as an addition to Facets, mainly for the reason headius mentions above, it's the simplest filter available. I'm still torn on the name, but for some reason #self didn't seem right. For my own extension library I finally went with #it.
----------------------------------------
Feature #6373: public #self
https://bugs.ruby-lang.org/issues/6373#change-28542

Author: trans (Thomas Sawyer)
Status: Assigned
Priority: Normal
Assignee: matz (Yukihiro Matsumoto)
Category: core
Target version: 2.0.0


=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
