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.
