3e3cc2a6d6 dict.pop: Remove default for second argument (#7481) 
The first overload takes care of the case where there is only one argument, so there should be no default in the second overload.

9796b9ed69 Improve open overloads when mode is a literal union (#7428) 
As pointed out by @gvanrossum in https://github.com/python/typing/issues/1096

Improves type inference in cases when we know that mode is
OpenBinaryMode, but don't know anything more specific:
```
def my_open(name: str, write: bool):
    mode: Literal['rb', 'wb'] = 'wb' if write else 'rb'
    with open(name, mode) as f:
        reveal_type(f)  # previously typing.IO[Any], now typing.BinaryIO
```

You may be tempted into thinking this is some limitation of type
checkers. mypy does in fact have logic for detecting if we match
multiple overloads and union-ing up the return types of matched
overloads. The problem is the last overload interferes with this logic.
That is, if you remove the fallback overload (prior to this PR), you'd get
"Union[io.BufferedReader, io.BufferedWriter]" in the above example.

7c4ca27083 builtins.filter compat with typing.TypeGuard (#6726) 
This change enables the following use-case:
```python
def is_not_none(x: Optional[int]) -> TypeGuard[int]:
    return x is not None

list_optional: list[Optional[int]] = [0, None, 1, None, 2]
generate_ints: Iterable[int] = filter(is_not_none, list_optional)
```
