**What it does**
|

|
||||
Checks for invalidly defined `NamedTuple` classes.
|
||||
|
||||
**Why is this bad?**
|
||||
|
||||
An invalidly defined `NamedTuple` class may lead to the type checker
|
||||
drawing incorrect conclusions. It may also lead to `TypeError`s at runtime.
|
||||
|
||||
**Examples**
|
||||
|
||||
A class definition cannot combine `NamedTuple` with other base classes
|
||||
in multiple inheritance; doing so raises a `TypeError` at runtime. The sole
|
||||
exception to this rule is `Generic[]`, which can be used alongside `NamedTuple`
|
||||
in a class's bases list.
|
||||
|
||||
```pycon
|
||||
>>> from typing import NamedTuple
|
||||
>>> class Foo(NamedTuple, object): ...
|
||||
TypeError: can only inherit from a NamedTuple type and Generic
|
||||
```

This is\nmainly beneficial for type checkers. But, if the `@overload` usage is invalid, the type\nchecker may not be able to provide correct type information.\n\n## Example\n\nDefining only one overload:\n\n```py\nfrom typing import overload\n\n@overload\ndef foo(x: int) -> int: ...\ndef foo(x: int | None) -> int | None:\n return x\n```\n\nOr, not providing an implementation for the overloaded definition:\n\n```py\nfrom typing import overload\n\n@overload\ndef foo() -> None: ...\n@overload\ndef foo(x: int) -> int: ...\n```\n\n## References\n- [Python documentation: `@overload`](https://docs.python.org/3/library/typing.html#typing.overload)",
