Just to clarify, we currently have the abstract data type for Core,
that will remain unchanged.

We use DrIFT plus some horrible binary instances to automatically
generate an on-disk format, which is a but yuk, and quite slow. We are
going to move to Data.Binary, which will give us a documented,
consistent, smaller and faster on-disk binary representation.

If you use the Yhc.Core API you will not notice any changes.

Thanks
