| * @assertion 15.10.2.6: The production Assertion :: ^ evaluates by returning an |
| * internal AssertionTester closure that takes a State argument x and performs |
| * the following: |
| * <li>Let e be x's endIndex. </li> |
| * <li>If e is zero, return true. </li> |
| * <li>If Multiline is false, return false. </li> |
| * <li>If the character Input[e-1] is one of LineTerminator, return true.</li> |
| * <li>Return false.</li> |
| * </ol> |
| * @description Checks that the ^ assertion is interpreted correctly. |
