Does functools.update_wrapper() *copy* __doc__ and __annotations__ or *reference* those function/method attributes so that the API docs have the docstrings and tools with type annotation support have the correct type annotations? https://docs.python.org/3/library/functools.html#functools.update_wrapper
Right at the top of the page is a link to the source code, so you ought to be able to tell from reading the source, which is in Python. I would expect that since __doc__ is a string or None, and in both cases immutable, copying it would be a waste of time. (And impossible in the case of None.) I'm gratified to see from the source that I'm correct: update_wrapper calls: setattr(wrapper, attr, value) not setattr(wrapper, attr, copy.copy(value)) or similar. Does that answer your question? If I have misunderstood your question, please clarify. -- Steven
