There was a problem hiding this comment.
You used Union as a return type. In Mypy, this means that code that uses values returned from this method will trigger errors if the usage is valid for a single type only. This is why in general we're avoiding using Unions as return values.
Is this intended, @vlasovskikh?

@ambv You're right. object.__reduce__ always returns a tuple unless it's overridden in inheritors. So inheritors are free to specify str or tuple or a specific tuple as the actual return type of the override.
It's up to its inheritors to return either a tuple or a string.
