If the lazy evaluation of annotations (PEP 563) also lands in 3.7, then this would be a very minor downside. You'd need to pip-install typing as well as mypy *for the actual type checking*, but at run time, you could ignore both (all those List[...] annotations would be stored unevaluated). Otherwise, it'd mean that any project that makes use of type hints would require typing as a run-time dependency.
