Cannot instantiate Type[Type[...]]

Bug Report

Mypy thinks that Type[Type[...]] cannot be instantiated. I understand that it can be difficult to support, but is there any reason to consider it an error?

Type[Type[something]] is type or its subclass. It can be instantiated (code below runs without errors).

To Reproduce

Write the following code, run mypy on it.

class A:
    pass

B = type(A)('B', (A,), {})
b = B()

Playground

Expected Behavior

No errors (but I'm not sure that I'm not just missing something and under certain circumstances such code can be incorrect).

Actual Behavior

mypy reports:

main.py:4: error: Cannot instantiate type "Type[Type[A]]"

Your Environment

• Mypy version used: 0.941 latest (from pip & playground)
• Mypy command-line flags: nothing
• Mypy configuration options from mypy.ini (and other config files): nothing
• Python version used: 3.10
• Operating system and version: Ubuntu 22.04

Inizia inserendo le definizioni delle classi riportate e la chiamata a type() in main.py ed eseguendo mypy con la configurazione Python 3.10 indicata per riprodurre la diagnostica. Traccia la gestione di Type[Type[A]] e aggiungi un test di regressione che copra questo caso; il lavoro è completato quando mypy accetta l’esempio senza indebolire i controlli di istanziazione non correlati.
