| * @assertion Evaluation of a throw expression of the form throw e; proceeds as |
| * follows: |
| * The expression e is evaluated yielding a value v. |
| * If v evaluates to null, then a NullThrownError is thrown. Otherwise, control |
| * is transferred to the nearest dynamically enclosing exception handler, with |
| * the current exception set to v and the current return value becomes |
| * undefined. |
| * @description Checks that attempting to throw null in any manner results in |
| * NullThrownError being thrown instead. |
