Subject: [ruby-core:45808] [ruby-trunk - Feature #6373] public #self


Issue #6373 has been updated by marcandre (Marc-Andre Lafortune).


I second the addition of `Object#self`.

For the objection that `self` is a keyword, so is `class`. And there wouldn't ever be a need to call `self.self` :-)

Do we need a slide-show for this?

=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.
