/// @assertion Case ⟨Setter: Late-final variable with no declared type, no
/// initialization⟩. A variable declaration of the form static? late final id;
/// implicitly induces a setter with the header void set id(dynamic x). An
/// execution of said setter in a situation where the variable id has not been
/// bound will bind id to the object that the argument x is bound to. An
/// execution of the setter in a situation where the variable id has been bound
/// to an object will incur a dynamic error
///
/// @description Checks that the static type of an implicit setter of a late
/// final instance variable with no declared type and no initialization is
/// `dynamic`
