                    including the original.

      \:            Repeats the previous pattern at least once,
                    including the original; that is, a null occurrence
                    does not match.

                    letters.

      \n            Any alphanumeric character.

      \s            Any character that can be used in a symbol:
                    alphanumeric, dollar sign, and underscore.

      \l            Any lowercase letter.

      \u            Any uppercase letter.

   uppercase letter:
