It's easy to avoid: just don't put subtying in the language design.
Much of the talk in language design in the last ten years or more
has focused on various mechanisms for subtyping, but it's an
entirely optional language feature. That's easy to forget when
it's all anyone's talking about, but it is possible to just leave it
It's also possible to leave a static type system out entirely.
Whether it is a good decision to do so will depend on a number of factors. But I consider it important to keep in mind that it is a deliberate choice.
