/// @assertion If an exception is raised during execution of an on-catch clause,
/// this will transfer control to the handler for the finally clause, causing
/// the finally clause to execute in this case as well.
///   If no exception was raised, the finally clause is also executed. Execution
/// of the finally clause could also raise an exception, which will cause
/// transfer of control to the next enclosing handler.
/// @description Checks that a throw statement inside a finally clause replaces
/// the current exception and unwinds the call stack from the new location.
