PEP 526: Name mangling doesn't take place inside the body of a module

Hi,
In PEP 526, there is a section called "Runtime Effects of Type Annotations" which has the following code:

from typing import Dict
class Player:
    ...
players: Dict[str, Player]
__points: int

print(__annotations__)
# prints: {'players': typing.Dict[str, __main__.Player],
#          '_Player__points': <class 'int'>}

The code and the output don't match.
Name mangling only happens inside the body of the class not module. So the correct output would be:

{'players': typing.Dict[str, __main__.Player], '__points': <class 'int'>}

If we want to see the effect of name mangling we could have something like:

from typing import Dict

class Player:
    __points: int

players: Dict[str, Player]
print(__annotations__)
print(Player.__annotations__)

Or have the print(__annotations__) inside the class:

from typing import Dict

class Player:
    __points: int
    print(__annotations__)

players: Dict[str, Player]
print(__annotations__)

That would be a quick fix if you confirm.

Apri PEP 526 e rivedi la sezione “Runtime Effects of Type Annotations”, in particolare il relativo esempio di annotazione a livello di modulo e l'output visualizzato. Conferma il comportamento di name-mangling rispetto all'esempio, quindi aggiorna il codice o l'output in modo che concordino e mantengano una dimostrazione chiara del mangling a livello di classe. Il lavoro è concluso quando il PEP renderizzato non presenta più risultati contraddittori.
