EC4 - False positives with TypeVar

[Horrih]

Describe the bug
When using python's TypeVar mechanism for type annotations, EC4 code smell is triggered.
This should not be considered a code smell since using it in global scope is the standard way.

To Reproduce
Example straight from the python official documentation

Expected behavior
Do not flag this as an error

Hi @Horrih,
thank you for the issue.
What do you think about it @jhertout ?

Hi @Horrih,
I try to reproduce the problem but without success.

Here is my tests.

TEST 1

using strictly your example => NO PROBLEM on local Unit test

from collections.abc import Sequence
from typing import TypeVar

U = TypeVar('U')

def second(l: Sequence[U]) -> U:
return l[1]`

TEST 2

with a new line added => there is a real problem as expected at the line with "#noncompliant"

from collections.abc import Sequence
from typing import TypeVar

U = TypeVar('U')

def second(l: Sequence[U]) -> U:
print(U) #Noncompliant
return l[1]

Do you still have the problem ?
Can you give me a screenshot of the problem, please ?
Can you give me the version of SonarQube and the version of your installed python plugin, please ?
