module Sass::Script::Value
  # A SassScript object representing a null value.
  class Null < Base
    # The null value in SassScript.

    # This is assigned before new is overridden below so that we use the default implementation.
    NULL = new(nil)

    # We override object creation so that users of the core API
    # will not need to know that null is a specific constant.
    #
    # @private
    # @return [Null] the {NULL} constant.
