Description
Bug Report
Prior to mypy 1.7, we were able to add decorators on top of properties by adding a # type: ignore comment. In 1.7.1, the decorated attribute now errors on access with not callable [operator].
To Reproduce
https://mypy-play.net/?mypy=1.7.1&python=3.11&gist=12b3add6be6394238695b9b42c79d425
Expected Behavior
No errors.
Actual Behavior
main.py:20: error: "MyObj" not callable [operator]
Found 1 error in 1 file (checked 1 source file)
