Very nice! And a great introduction to some of the finer points of Sage. I'd think it would be useful for users or developers-to-be that are curious about preparsing, coercion, interface types, design choices, Sage culture and history, etc. Maybe Harald can slot it into the website someplace appropriate where it'll be seen by the right audience.
