      # This cop checks if the length of a method exceeds some maximum value.
      # Comment lines can optionally be ignored.
      # The maximum allowed length is configurable.
      #
      # You can set literals you want to fold with `CountAsOne`.
      # Available are: 'array', 'hash', and 'heredoc'. Each literal
      # will be counted as one line regardless of its actual size.
      #
      # @example CountAsOne: ['array', 'heredoc']
      #
      #   def m
      #     array = [       # +1
      #       1,
      #       2

      #     hash = {        # +3
      #       key: 'value'
