cell-var-from-loop (W0640): why

[bersbersbers]

Bug description

I don't see why the code in this example file

https://github.com/PyCQA/pylint/blob/96e84595194073ea54a8c7730b86125049c0f4f9/tests/functional/n/nested_func_defined_in_loop.py#L1-L10

is problematic. When called using example(range(4)), it outputs

0
1
2
3
0
1
2
3

which looks correct to me. See also https://github.com/vald-phoenix/pylint-errors/issues/7
