/// @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 an expression statement of the form "throw e;"
/// indeed raises an exception and transfers control to the nearest enclosing
/// exception handler if there is one.
