 at all? As I understand this method is just a tap that doesn°«t need a
 block.
 
 That depends on the contract. I was under the impression that #itself (or
 whatever name) in block form would return the value of the block. e.g:
 
   def tap
     yield self if block_given?
     self
   end
   def itself
     if block_given?
       yield self
     else
       self
     end
   end

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.
