/// @assertion Evaluation of an assignment a of the form v = e proceeds as
/// follows:
/// Let d be the innermost declaration whose name is v or v =, if it exists.
/// ...
/// If d is the declaration of a local variable, the expression e is evaluated to
/// an object o. Then, the variable v is bound to o unless v is final or const,
/// in which case a dynamic error occurs. If no error occurs, the value of the
/// assignment expression is o.
/// @description Checks that the value of the assignment expression of the form
/// v = e is o.
