Understand Side Effects on Classes/Instances

[davidhalter]

Quite a few cases where jedi struggles to understand code are related to people modifying classes from the outside.

A typical example would be:

class A():
    def __init__(self):
        self.x = None

a= A()
a.x = 3
# At this point if you complete a.x, jedi still thinks x is None.

Obviously there are much more complicated examples as well.

For performance reasons this will definitely not happen in Jedi. Might happen if I ever rewrite it in Rust. You can also follow #1059, there I will update if something happens in that direction.
