It's not just the documentation, it's the interface.  Having to walk 
linked-lists of graphically unlinked objects is bad.  Having to use 
boilerplate to find the head of a glist just to create a scalar is bad.

I think Pd-l2ork is getting close to a release with my new data 
structure stuff in it.  It's a first step at addressing some of these 
issues.
