Confusing error: incompatible type "Type[bytes]"; expected "Type[bytes]"

Bug Report

Error message seems to indicate it requires the type it is getting. I could be reading the error message wrong, but this one confuses me.

To Reproduce

1. put the code in a file e.g. scratchpad.py

   from typing import Type
   
   def f(class_type: Type[object]):
       if class_type in [bytes, bytearray]:
           return True
   

2. run mypy scratchpad.py

Expected Behavior
no errors

Actual Behavior

scratchpad.py:4: error: List item 0 has incompatible type "Type[bytes]"; expected "Type[bytes]"

Your Environment

• Mypy version used: 0.790
• Mypy command-line flags: n/a
• Mypy configuration options from mypy.ini (and other config files): n/a
• Python version used: 3.8.3
• Operating system and version: OSX 10.15.7

Inizia eseguendo mypy sull’esempio scratchpad.py dell’issue e conferma la diagnosi contraddittoria Type[bytes]. Traccia il percorso di controllo dei tipi coinvolto nell’espressione di appartenenza a una lista; il lavoro è concluso quando l’esempio valido non segnala alcun errore, come descritto in Expected Behavior.
