No, not really.
I can replace \score {} with (ly:make-score) but that doesn't really help me.
I have no idea how to map the nesting of the parallel contexts to Scheme 
expressions within a single expression.

(get-staff returns Staff objects, but at a later (or earlier) point I will also 
want to create the Staff with Scheme (the music itself will stay in LilyPond 
language files).
