Yeah I see what you mean, you can always disable specific features, but I think that's a habit mypy tries to enforce. They consider redefining a variable bad practice.

Even in rust you have to be explicit about doing the same thing with an extra "let" statement.

Yeah that's fair enough, and I've lived with it because of how good MyPy is. But I always end with weird variable names like uuids_as_list as a result!
