/// @assertion Case ⟨Setter: Mutable variable with no declared type, with
/// initialization⟩.
/// A variable declaration of the form static? late? var id = e; implicitly
/// induces a setter with the header void set id(dynamic x), whose execution
/// sets the value of id to the incoming argument x.
/// Type inference could have provided a type different from dynamic.
///
/// @description Checks that the static type of an implicit setter of a mutable
/// variable with no declared type but with an initialization is provided by the
/// type inference. Test that it is a compile-time error to pass a parameter of
/// type `num` to implicit setter of type `int`
