Looks good, update CHANGELOG?

Is there anything we can do to test this in a way that we don't forget next time?

Hello @florianvazelle, please respond to the following #399 (comment). Thanks

@florianvazelle, Could you please finish this PR when you have a moment? Thank you!

Hi @saimedhi, sorry I'm taking some time to study solutions to have a correct stubs package.

The only real way I've found is to use stubtest, but that only ensures that the definitions in the stubs package are defined in the package at runtime too (no extra definitions) and logical with what is defined in the package at runtime (same parameters ...), but if a definition is missing in the stubs package it won't be raised.

I'm going to add this to the linting commands anyway.

To prevent oversights from happening again, I suggest opening a new issue to study solutions, and we'll can then merge this PR.

@florianvazelle I finished #536 so types are back in the game. Do you want to finish this?

I am not sure we need to declare types like this here. For other types we just do self.cat = CatClient(self) and I think the Python type system is smart enough to figure out that cat is always CatClient, but I could be wrong. So either add types as proposed here or remove the declaration?

@dblock I think you fix my issue with #536, I'm closing this PR
thank you 😉

Did I? This code says Any, should it be typed or should the declaration be removed?
