Thanks to everyone who responded.

The reason I ask is because I've just spent the weekend battling with
doctests of decorated functions, and discovering that without
functools.wraps() all my doctests weren't being called. I'm wondering
whether it would be a good idea for doctest to auto-detect tests in

This is not needed if you call wraps() appropriately, but you might not
always do that.
