The following code triggers incorrect warnings:
I052 main class definition should start with a "class Name("
I053 each base class should be seperated by a new-line

@decorator
class DecoratedClass(
    ClassBase,
):
    pass

The following code triggers incorrect warning:
I045 each subentry opener must be in its own line

dict_obj = {
    'stuff': [
        [],
    ],
}

While trying to make function calls from as a function parameter, Flake8 raises I081 warning, though function calls are not mutable.
For example, the following code raises I081 (b parameter):

def hello(
    self,
    x: str,
    b: str = fastapi.Header(None),
)

The black autoformatter is pretty popular and also opinionated. What is the relationship between flake8-intsights and black?

(Side questions: why "intsights"? should it be "insights" and was a typo?)

The following code triggers the following incorrect warning: E302 expected 2 blank lines, found 0

class Example(

@decorator_func
def example():
    print('stuff')

The following code triggers an incorrect warning (I006 indentation should be gradually added):

class A:
    def __init__(self):
        text_block = '''
this file has weird indentation.
'''
        print(text_block)
