Bug Report
I was really excited to see #13513 merge but trying it out seems like it doesn't actually type-check things
here's a small example
# main.py
from typing import Protocol
class P(Protocol):
def f(self) -> str: ...
import t
t_p: P = t # expect an error here, it does not match P# t.py
def f() -> int:
return 6I expect this to error because the f inside t returns int but the protocol specifies it should return str.
additionally, I think I should also be able to write something like this, but it currently errors for an unrelated reason (even when the module matches the protocol):
from typing import Protocol
class P(Protocol):
def f(self) -> str: ...
t: P
import t # error: Name "t" already defined on line 6Your Environment
