I agree with you -- but I also don't say no to free food.

I mean regardless of whether mypy was going to make my code run faster I would have used it for the shear confidence it gives wrt to my code correctness. The fact that I can use that same code (untouched) to speed it up... that's just means I get to have my cake and eat it too :P

Yeah this is exactly it for me. I already had type annotations and ran mypy to help with correctness. And I tried this out because it felt like a nice thing to get for free.
