Martin, there are two reasons for hiding away these details:
1. we need to be able to change the codec state without
breaking the APIs
2. we don't want the state to be altered by the user
A single object serves this best and does not create
a whole plethora of new APIs in the _codecs module.
This is not over-design, but serves a reason.
