Here the implementation. This is my first patch to Ruby so I'm not sure it is correct. Let me know if I need to change something.

Feature #6373: public #self

This was recently suggested to me as an extension:

~~~ruby
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.
