Attempted to reuse member name in Enum definition

[lanzz]

I'm trying to follow the dynamic generation of Enum values example as described in the Enum documentation, and I'm getting this from mypy:

example.py:23: error: Attempted to reuse member name "i" in Enum definition "Slot"  [misc]

Now, I am trying to reuse the member name; in contrast to the Enum example, I have multiple loops that generate several sets of Enum values, and I am reusing the same loop variable across all of them (see the example below). mypy doesn't complain if I only have one loop in my Enum.

But considering I've already declared that member to be ignored in _ignore_, I don't see why I should use multiple distinct loop variables for all my loops, if all of them are going to be ignored by Enum plumbing anyway.

Moreover, the loop variable is used in a loop anyway; it will definitely get reassigned multiple values even during the first loop execution. I don't see how having multiple loops makes any difference to having a single loop.

To Reproduce

Run source through mypy:

import enum


class MyEnum(enum.StrEnum):
    _ignore_ = 'MyEnum i'
    MyEnum = vars()

    for i in range(8):
        MyEnum[f'SOMETHING_{i}'] = f'Something{i}'

    for i in range(4):
        MyEnum[f'ANOTHER_{i}'] = f'Another{i}'

Expected Behavior

mypy should not complain about this code.

Actual Behavior

mypy complains about the member being reused at the line of the second loop.
