Yes, why do something automatically when you can do manual work!

  I think the idea is that you have to write tests anyway.

    No, you don't have to write tests for invariants enforced by the type system.

      I think the bigger idea is that people who've never actually written serious code in a dynamically-typed language assume that people who do always write a bunch of extra unit tests to assert correct types, assert behavior on incorrect types, etc. etc., and that programs crashing due to type errors is a super frequent occurrence. None of those things are true.

        And yet there are dynamic language proponents in this very subthread suggesting that's exactly what everyone should do.
