While I would like to some day, I'm not currently teaching perl, and so don't have a syllabus to make suggestions from. merlyn, however, does.
What about creating rules that could be exported individually, then using those to create progressive bundles (:lesson1, :lesson2) that would mirror a lesson plan? That way a teacher could tailor usage to their particular syllabus OR use the pre-made bundles? Autodidacts could also just plug in the right bundle to keep them on course, or eliminate specific rules as they get the hang of things.
Perhaps it would be useful to create another meditation node focusing on picking out specific rules and creating a good, general syllabus (unless you adopt the current stonehenge one)? Most of my suggestions right now would probably mirror the chapters of the llama books, as that's how I learned it.
