Even beyond that, if you've imported `from foo import bar` and then `from something import *`, it might work just fine. Then you upgrade the `something` module, and it happens to now include an item named `bar`, and you're suddenly breaking your existing usage without ever having changed your code. Star imports are convenient, but dangerous in so many subtle ways. There's a very good reason that every major Python linter will call this out as bad behavior.
