An afterthought, however: we do have an inordinate amount of user-level
commands that need to be called from Scheme rather than with Lilypond
syntax. That does not make sense. Void music functions have been
around for eternities, just a bit inconvenient to define, but reasonably
documented.
Maybe we need a user interface meister that tries to maintain a bit of
coherency and sanity when new features get added.
