…This commit includes: 1. Parser updates 2. AST updates 3. typing.py updates 4. Unit tests It does not include the following: 5. Symtable updates 6. Compiler updates 7. C implementations of TypeVar, TypeVarTuple, ParamSpec, Generic
This fixes compilation for me locally.
This isn't fully functional, but it should be enough to unblock work on the runtime. I'll update this PR as I implement more.

I think the refleaks are unrelated, probably #104510. |
Yeah, you're right. |

Congrats! Really excellent work on a tight timeframe. |

Awesome! But will python support from typing import Protocol
class Dance(Protocol):
def dance(self): ...
class Sing(Protocol):
def sing(self): ...
def perform[P: Dance + Sing](person: P):
person.dance()
person.sing() |
It will not, at least not soon. Changes like this often need a PEP. If you are interested in it, new ideas are welcomed at https://discuss.python.org/c/ideas/6. As for this specific question, I think you are asking for a https://discuss.python.org/t/type-intersection-and-negation-in-type-annotations/23879 |

Adding the feature like a I hope that the adoption of PEP695 will lead to more discussion on this as well and improve the representation of type hints. |

A C-accelerator was introduced for the typing module in Python 3.12 (see python/cpython#103764). Because a pure python source is no longer available, now we stub out the missing classes and provide some __class_getitem__ methods to allow subscripting like Type[int]. This may mean when 3.12 is the minimum, we can remove older brain features like infer_typing_alias().
