It was on the cards for GDP, but was dropped quite early on due to
insufficient resources.  IIRC at least three people "really
wanted" to rewrite the Scheme chapter, but I had to tell them all
to focus on NR 1+2.

Not only that, but simply thinking about music expressions
requires a certain amount of programmer-like thought.  I still see
newbies posting here when their misunderstanding traces back to
not understanding music expressions... but hopefully that will
lessen once 2.12 is out and people read the updated tutorial.

Stuff along those lines are planned for GOP... but just like the
extent of doc work in GDP, it all depends on the amount of time
and effort that users are prepared to give.
