I may be dull, but it wasn't until I started using Python 3 that it really clicked in my head what encode/decode did exactly. In Python2 I just sort of sprinkled one or the other when there was errors until the pain stopped. I mostly attribute this to str.decode and bytes.encode not existing.
This is a key observation. It's also now much easier to explain what's going on and recommend correct code in Python 3, so overall it's a win.
That's not to downplay the inconvenience of not being able to easily do bytes->bytes or str->str transformations as easily as was possible in Python 2. I've not thought about it much, but placing those types of transformations on a different set of functions (methods or builtins) seems like the right direction. IOW, don't mess with encode/decode.
