/// @assertion Execution of a finally clause finally s of a try statement
/// proceeds as follows:
///   Let x be the current exception and let t be the active stack trace.Then
/// the current exception and the active stack trace both become undefined. The
/// statement s is executed. Then, if x is defined, it is rethrown as if by a
/// rethrow statement enclosed in a catch clause of the form catch (vx, vt) where
/// vx and vt are fresh variables bound to x and t respectively.
/// @description Explicitly checks that if no matching catch clause was found for
/// the current exception, control is transferred to the nearest dynamically
/// enclosing exception handler.
