I find myself wishing for an O'Reilly style book "Hacking Lilypond". The user guide and the reference are fine as is, but a book with some extended examples of how to _architect_ solutions in Lilypond would be great.
I already know Scheme the language, and have a basic understanding of the Lilypond data structures, but advanced knowledge of Lilypond data structures and knowledge of its many functions escapes me for now. Quite often I find myself wondering "What _api_ do we use to access _this_ data structure?" In the past I found the answer was often unclear without asking for assistance. Some data structures just get manipulated with the usual list functions, other areas some kind of function/iterator needed calling. Things appear to be getting better on the Scheme front, though, with some of the recent improvements in integration between Lilypond markup and Scheme code.
