Ah, I see. If this is intended behavior (which is sounds like it is?) feel free 
to close. Thanks!

[issue40595] AttributeError from type annotation

2020-05-11 Thread Taylor Robie


New submission from Taylor Robie :

Consider the following:
```
import re

class MyClass(object):
def re(self):
pass

def foo(self, m: re.Match):
pass
```

Even though `re` and `MyClass.re` are distinct namespaces, the type annotation 
misses that fact (presumably there is an issue with how it is parsing the AST) 
and attempts to access MyClass.re.Match, resulting in:

`AttributeError: 'function' object has no attribute 'Match'`

Commenting out the definition of `MyClass.re` or reversing the definition order 
resolves the issue.
