I'd be a little concerned about wholesale wrapping of functions, purely from the perspective that you'll be wrapping mostly side-effect free functions with functions that do have side-effects. That sounds like something you'd want to do consciously, where you know it will be safe, and where the results will be meaningful ( I imagine that logging inside retry blocks could reduce your logs to meaningless pudding pretty quickly ). On the other hand, I could just be being paranoid.
