/// @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 when another exception is raised in a catch clause,
/// the finally clause of the same try statement is still executed, other catch
/// clauses of that try statement aren't, and control is transferred to the
/// nearest enclosing exception handler afterwards.
