Playground: https://mypy-play.net/?mypy=latest&python=3.12&gist=6ae94d19a2160b47cd3c3f2f0bc96553

This code does not produce a [deprecated] error:

# mypy: enable-error-code = deprecated
from typing import overload
from typing_extensions import deprecated

class Some:
 @overload
 @deprecated("reason2")
 def some(self) -> None: ...
 @overload
 def some(self, x: int) -> None: ...

Some().some() # no error here!

However, this one does:

@overload
@deprecated("reason1")
def func() -> None: ...
@overload
def func(x: int) -> None: ...

func() # E: overload def () of function __main__.func is deprecated: reason1

Version:

» mypy --version
mypy 1.15.0+dev.c9ed867352b0be6b2cca9df3c856f9047409751b (compiled: no)

Strange. I will have a look at it. Thanks for reporting!

Is it fixed by #18333, by any chance?

[sobolevn]

Nope :(

Using the same gist:

(.venv) ~/Desktop/mypy master ✗ 
» gh pr checkout 18333 

» mypy ex.py
