ok, I see, the story is a bit more complicated ... simply wrapping
lilypond syntax in a displayMusic block in a program 

 ,----

 |       \displayMusic { c'4\f }
 |     }
 `----

for producing the desired internal list representation then seems like
the best option. Thx.

I still like it if it outputs parser information as nested lists to be
consumed by other lisps 'as-is' ;)
