This will add some overhead for every single call to such wrapped function. If you use that extensively for many classes, won't that be a huge performance degradation? It would maybe be nice to have a flag so that these wrappings apply only in test or debug mode. Also, it works e.g. by using `inspect.currentframe().f_back.f_back`. I'm not sure if that is such a clean and stable solution. (See e.g. here: https://github.com/amitassaraf/lang/blob/master/src/lang/acc...) E.g. when you add other wrappers around your function, I'm quite sure that this would break.
