Subject: [ruby-core:44704] [ruby-trunk - Feature #6373][Open] public #self


Issue #6373 has been reported by trans (Thomas Sawyer).

----------------------------------------
Feature #6373: public #self
https://bugs.ruby-lang.org/issues/6373

Author: trans (Thomas Sawyer)
Status: Open
Priority: Normal

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.
