Type[type] is not indexable when in Union

[jolaf]

The following code:

t = type[str] | type[bytes]

produces the following output:

$ mypy test.py
test.py:1:5: error: Value of type "Type[type]" is not indexable  [index]
    t = type[str] | type[bytes]
        ^
Found 1 error in 1 file (checked 1 source file)

This looks like a false positive to me.

$ mypy --version
mypy 0.961 (compiled: yes)

$ python3 --version
Python 3.10.4

$ lsb_release -d
