Private/protected functions inaccessible through list comprehensions

[LeicaSimile]

Calls to functions marked as private/protected throw an error when inside a list comprehension. Example:

class Test:
    def a(self):
        return [self.b(x) for x in "12345"]

    @private
    def b(self, x):
        return f"{x}."

 
t = Test()
t.a()

Error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 3, in a
  File "<stdin>", line 3, in <listcomp>
  File "/.venvs/test/lib/python3.10/site-packages/accessify/access.py", line 75, in private_wrapper
    raise InaccessibleDueToItsProtectionLevelException(
accessify.errors.InaccessibleDueToItsProtectionLevelException: Test.b() is inaccessible due to its protection level

In accessify, it seems to be raised here:

# access.py
            ...
            method_caller_frame = inspect.currentframe().f_back
            method_caller_class = get_method_class_by_frame(frame=method_caller_frame)

            if instance_class is not method_caller_class:
                raise InaccessibleDueToItsProtectionLevelException(
                    INACCESSIBLE_DUE_TO_ITS_PROTECTION_LEVEL_EXCEPTION_MESSAGE.format(
                        class_name=instance_class.__name__, class_method_name=method.__name__,
                    ),
                )

Removing the private/protected decorator makes the error go away, as does rewriting the list comp to a for-loop assignment. Perhaps related to Python 3's scoping for list comprehensions - can there be a workaround?

Tested on Python 3.10.6
