Tab complete for class __call__ not working

[MarcoGorelli]

What follows is an issue I originally reported to IPython, but was asked to report here (original issue: ipython/ipython#14184)

---

If I make the following two files:

# t.py
class MyClass:
    def my_method(self) -> None:
        print('this is my method')


def foo() -> MyClass: return MyClass()

and

# f.py
class MyClass:
    def my_method(self) -> None:
        print('this is my method')

class Foo:
    def __call__(self) -> MyClass:
        return MyClass()

foo = Foo()

then foo().my_method() works for both

But - I only get the auto-complete suggestion for the first one: ipython -i t.py:

ipython -i f.py:

Shouldn't both autocomplete to the method available in MyClass?

For reference, this came up here pola-rs/polars#11433

I agree that this should probably work, but it's not a normal Jedi case due to the fact that the source code is not available anymore (for Jedi). I feel like we should fix this, but at the same time I understand very well why this didn't work in the first place.
