Currently, I can do this:

  class A
    def self.a
      puts "A.a"
    end

    def b
      self.class.a
    end
  end

but it doesn't work with derived types:

  class B < A
    def self.a
      puts "B.a"
    end
  end
  b = B.new
  b.b #=> B.a

Perhaps it would be nice if I could get information about the current
method being executed:

  class A
    def b
      thismethod.class.a
    end
  end
  b = B.new
  b.b #=> A.a

Just a thought.
