Description
I realized that when using Python built-in dataclasses, the following scenario is not detected:
from dataclasses import dataclass
@dataclass
class MyClass:
val = [] # Mutable data structure
Given the presence of the dataclass decorator, the signature of the __init__ method for MyClass is the following one:
def __init__(self, val = []):
I have seen that the rule B006 is supposed to detect issues where mutable data structures are used in a function signature. This is a slightly different scenario but with the same output if this effect is not intended. I could not find any related issue. Was this issue reported before?
