The Manifold project [1] nicely illustrates the author's proposition regarding structural typing and static type systems. Using the Manifold library you can indeed create structural interfaces [2] in Java similar to those in TypeScript. Manifold also enables the use of structural interfaces with Maps, it's pretty amazing.
