RawErasureCoder is not really doing encoding/decoding by its interfaces declared. This sounds to some helper interface for real encode/decoder interfaces. It's a good thought. Yes itself doesn't do any real work but is just a helper, on the other hand, it also serves as a good concept for our discussion since it's not convenient to mention encoder or decoder in many general aspects. You're right I need to update the comments to make it accurate.
