- output type errors now redirect users to the type-neutral convenience functions in the codecs module - stateless errors that occur during encoding and decoding will now be automatically wrapped in exceptions that give the name of the codec involved Wouldn't it be better to add an annotation API to the exceptions classes? This would allow to annotate all exceptions without having to replace the exception object.

There's a reason the C API for this is private - it's a band aid fix, because solving it properly is hard :)

http://bugs.python.org/issue18861 covers the fact this is just one instance of a broader category of related problems related to providing good exception context information (and the issue started with a different one).

Cheers, Nick.
