I agree with Batuhan. Although bytecode for class annotations seems inefficient, it is difficult to optimize without breaking backward compatibility. You can write arbitrary code in class/module block which dynamically manipulate __annotations__. ``` class Foo: __annotations__["spam"] = "list" ham: tuple ```
