Re: \bookpart and variables

Interesting.  Note that

  foo = \relative c' { c d e f g }
  \bookpart {
    \foo
  }

  foo = \relative c'' { g f e d c }
  \bookpart {
    \foo
  }

fortunately works as expected (this is, different notes in different
\bookparts), while

  #(define notecolor blue)
  \bookpart {
    \score {
      { \override NoteHead.color = #(lambda (grob) notecolor)
        c1
      }
    }
  }

  #(define notecolor red)
  \bookpart {
    \score {
      { \override NoteHead.color = #(lambda (grob) notecolor)
        c1
      }
    }
  }

gives a red notehead both times.  So I think that your comparison is
not completely valid, since lilypond's `variables' are obviously
expanded at a different time than Scheme assignments.

Is this documented somewhere?
