The idea of replacing a function with its decorated version sounds cool, but what types of problems would I want to use this approach on? One thing that bothers me, is that once I decorate the function, I no longer have access to the original, un-decorated function. But on the other hand, if I had a decorator which I wanted to apply to multiple functions, then I would be DRY-er by taking this approach -- I would need only one decorator function and could then use it decorate as many other functions as it made sense to do so. So some guidance, please, on what types of problems this approach is useful for?
