Yes, but it's our parsers decision to give the scheme reader everything
it might want, even if that means chunking away from the lilypond code...

A scheme expression is embedded into lilypond syntax, so why can the
embedded expression decide where it ends, rather than the surrounding
LilyPond syntax?

This leads to situations like:
relative c'' {
  {\override NoteHead #'X-offset = #(+ 1 2)} c % works
  {\override NoteHead #'X-offset = #3} c       % doesn't work
}

Cheers,
Reinhold
