Yes.

Maybe 1~3%, but I am not sure. I am more interested in reducing number of
objects, because it will reduce import time.
Additionally, co_code is used while executing code. Unlike other cold data
(e.g. docstring, annotations), sharing co_code will improve CPU cache
utilization.
> Which functions have the same co_code?
For example,
```
# logging/__init__.py
@property
def manager(self):
return self.logger.manager
...
@property
def name(self):
return self.logger.name
```
Such simple functions are very common in OO-style code.
@Mark Shannon
Sure.
