I'm afraid, not really. The docs/sources contain the basics.

Sounds very interesting.

The design rationale is indeed a good starting point. There are some 
implementations writing geometry data: SVG, WKT, WKB. They all follow 
the tag dispatching approach, where functionality (e.g. coordinate 
writing) is used among the different geometries.

If you've specific questions, you can always ask them on the list.
