I think intrusive and non-intrusive examples are both needed
(maybe starting from an intrusive example). I believe more work
needs to be done in the extensibility aspect. This also includes
the fusion-converter I proposed sometime ago. I believe the more
easier it is to adapt Fusion to real world structures, the better.
