Make joins with Any more precise by ilevkivskyi · Pull Request #22336 · python/mypy

ilevkivskyi · 2026-10-31T00:33:54Z

Currently, we have join(Any, X) = Any, but this causes various false negatives. Some of these false negatives will be exacerbated by #22286. This PR makes join(Any, X) = X | Any (with obvious exceptions for object, Never, etc).

Note I also simplify/unify logic for callables by deleting combine_similar_callables().

Since this fixes false negatives I expect some fallout, but hopefully not too big.

Primer will be interesting! :-)

I had a feeling that dict would be painful

ilevkivskyi · 2026-10-31T01:08:12Z

Yes, this is essentially #5382. I will take a look at actual code examples, we may fix most cases with something similar to last_known_value for dict literals

ilevkivskyi · 2026-10-31T01:09:40Z

Or alternatively we can special-case dict: say if at least one value is Any, the whole thing is Any.

hauntsaninja · 2026-11-02T01:23:53Z

I would be okay with a dict special case

JukkaL · 2026-11-02T10:50:02Z

The dict special case is reasonable, since heterogeneous dicts are very common.

ilevkivskyi · 2026-11-02T17:06:51Z

OK, so I have spent some time playing with this. Couple things to note:

There are three different ways to special-case dict. First is to actually add a flag to a (big) bunch of functions (or a global state) to pass down to join_types(), second is to "manually" adjust value type for dict literals and dict() calls, third is to only special-case **kwwargs handling (where most of the errors come from). The first way is the only one that will allow to fully restore old behavior for dictionaries. The third one is the only one that will prohibit things like this:

a: Any
counts: dict[str, int] = {"hits": a, "misses": "42"}

Fixing #5382 by making Instance.last_known_value be LiteralType | TypedDictType | None is actually not hard by itself. The only hard part is avoiding false negatives in situations like this:

def foo(a: int, b: str) -> None: ...
def shuffle(d: dict[str, object]) -> None: ...

d = {"a": 42, "b": "yes"}
shuffle(d)
foo(**d)

(without also creating a bunch of false positives, in particular for something like log_call(d)). Note that plain assignments can simply invalidate last_known_value in the binder, and we can use index assignment to update the last_known_value.

@JukkaL @hauntsaninja Do you still prefer special-casing dicts? If yes, then which one of the three I mentioned?

ilevkivskyi · 2026-11-03T15:28:53Z

We discussed with @JukkaL that it is best to try special-casing ** for now. We can add a proper/better fix for ** in the future.
