  # Returns a hash that represents the difference between two hashes.
  #
  # Examples:
  #
  # {1 => 2}.diff(1 => 2) # => {}
  # {1 => 2}.diff(1 => 3) # => {1 => 2}
  # {}.diff(1 => 2) # => {1 => 2}
  # {1 => 2, 3 => 4}.diff(1 => 2) # => {3 => 4}
  def diff(h2)
    dup.delete_if { |k, v| h2[k] == v }.merge!(h2.dup.delete_if { |k, v| has_key?(k) })
