/// @assertion Case ⟨Setter: Late-final variable with declared type ⟩. A
/// variable declaration of the form static? late final T id; implicitly induces
/// a setter with the header void set id(T x). If this setter is executed in a
/// situation where the variable id has not been bound, it will bind id to the
/// object that x is bound to. If this setter is executed in a situation where
/// the variable id has been bound to an object, a dynamic error occurs
///
/// @description Checks that the static type of an implicit setter of a late
/// final instance variable with the declared type `T` is `T`
