- # Returns a decorator that invokes update_wrapper() with the decorated
- # function as the wrapper argument and the arguments to wraps() as the
- # remaining arguments. Default arguments are as for update_wrapper().
- # This is a convenience function to simplify applying partial() to
- # update_wrapper().
