And TDD is not the same as having tests, so please stop arguing for the second while pretending to be arguing for the first.

> In fact, strong type systems complement test-driven development very nicely. An expressive type system greatly simplifies testing because the compiler can catch a larger classes of mistakes and because - in the case of pure functions - the function signatures very clearly communicate the required input and output. There are no hidden dependencies and there's no setup or tear-down work required.
