  # Chained try
  #
  # Allows writing
  #
  #    str.ctry(:mb_chars, :downcase, :dasherize)
  #
  # instead of
  # 
  #    str.try(:mb_chars).try(:downcase).try(:dasherize)
  #
  # Only works for methods that dont have any arguments

  # Returns self. If given a block, it works a lot like Object#tap
  #
  # ==== Examples
  #
  #   [1,2,3,5,7].consecutive_by(:identity) 
  #   => [[1, 2, 3], [5], [7]]
