Yes, unfortunately...

That could be helpful!

I still need to wrap my head around how this framework/machinery works (or 
doesn’t) with true content-presentation separation; the example on the Google 
Code page has multiple "\context Staff” calls buried in the \violins note 
definition, which to my mind mixes content with presentation in an unfortunate 
way.

I’ll be interested in my testing to see what percentage of real-world scenarios 
this part represents.

That is a critical and wonderful feature.

Thanks,
Kieren.
