could you add a dynamic variant? e.g.

    dynamic qux = baz;

...and verify it also works

+  Expect.equals(42, baz.call(42));
+  Expect.equals(42, foo.call(42));
+  Expect.equals(42, bar(42));
+  Expect.equals(42, baz(42));
+  Expect.equals(42, foo(42));
+
+  baz = new Foo();
+  foo = new Foo();
+  Expect.equals('Foo42', baz.call(42));
+  Expect.equals('Foo42', foo.call(42));
+  Expect.equals('Foo42', baz(42));
+  Expect.equals('Foo42', foo(42));
+}
