Invalid Type sniffing with Fluent Design

[paulresdat]

Hello,

I think I ran across a bug working with this extension. For the most part it works well but it doesn't work with the fluent design it appears.

class IMyClass(metaclass=ABCMeta):
  def __subclasshook__(cls, subclass):
    return True

  @abstractmethod
  def do_something(self) -> IMyClass:
    raise NotImplementedError

  @abstractmethod
  def do_something_else(self) -> str:
    raise NotImplemented


class MyClass(IMyClass):
  def __init__(self):
    pass
  def do_something(self) -> IMyClass:
    return self
  def do_something_else(self) -> str:
    return 'hi'

mClass = MyClass()
x: str = ""
x = mClass.do_something().do_something_else()
print(x)

MyPy will say there is an error with the return value of do_something in regards to x and doesn't appear to take into consideration the chained method.

Let me know if I have this in error, but I think it's an actual bug.

UPDATE

You can close this issue. I jumped the gun too soon and found the issue with the variable name itself which I was overwriting. Your extension appears to work as it should given the example above. That is my fault. Have a good one.
