fooling around with some FauxO tooling

FauxO.py

from functools import wraps
from copy import deepcopy


def fauxothis(fn):
    @wraps(fn)
    def wrapper(self):
        new = deepcopy(self)
        fn(new)
        return new
    return wrapper

class Test(object):
    @fauxothis
    def stuff(self):
        self.hey +=1

# test
a = Test()
a.hey = 1
a.stuff()
# a.hey => 1
b = a.stuff()
# a.hey => 1
# b.hey => 2
