Steps to Reproduce and Observed Behavior

Example:

class Test():
    results: dict[str,str]
    def __init__(self):
        self.result = {}

This will currently result in a class with two attributes: results and the presumed typo result. And only the typo will get initialized!!!

Expected Behavior

The missing initialization of results being detected by the compiler (so that the typo can be found and fixed).
