Issue #6373 has been updated by Andrew Vit.


Rails ActiveSupport includes a similar method called `presence`. There is also a request to add block support to it, for a similar purpose: https://github.com/rails/rails/pull/13416#issuecomment-32636227

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.
