/// @assertion Evaluation of an assignment of the form e1.v = e2 proceeds as
/// follows:
/// The expression e1 is evaluated to an object o1. Then, the expression e2 is
/// evaluated to an object o2. Then, the setter v = is looked up in o1 with
/// respect to the current library. If o1 is an instance of Type but e1 is not a
/// constant type literal, then if v = is a setter that forwards to a static
/// setter, setter lookup fails. Otherwise, the body of v = is executed with its
/// formal parameter bound to o2 and this bound to o1.
/// @description Checks that in assignment of the form e1.v = e2 the body of the
/// setter v = i is executed
