| /// @assertion Execution of a rethrow statement proceeds as follows: |

| /// the immediately enclosing catch clause. |
| /// The current exception is set to p1, the current return value becomes |
| /// undefined, and the active stack trace is set to p2. |
| /// If f is marked async or async* and there is a dynamically enclosing exception |
| /// handler h introduced by the current activation, control is transferred to h, |
