Yeah, if you're going to use static type checks, which you should, you really want to run the checker in strict mode to catch oversights such as generic container types without a qualifier.

Although I've found that much of the pain of static type checks in Python is really that a lot of popular modules expose incorrect type hints that need to be worked around, which really isn't a pleasant way to spend one's finite time on Earth.

Typescript (and Flow to a lesser extent) had this problem once upon a time. It’s a lot better today, so I imagine it will continue to improve.
