Hi Harm,

Ooh! It even works outside of the parent variable (as would be absolutely 
necessary in my usage):

%%%  SNIPPET BEGINS
\version "2.19.80"

tee = #(define-music-function (name mus) (string? ly:music?)
  (ly:parser-define! (string->symbol name) mus)
  mus)

testing_this = {
  g'1
  \repeat volta 2 \tee MusicRi {
    c''1
    e''1_\markup \halign #-1.5 "Fine"
  }
  \repeat volta 2 {
    g''1
    d''1_\markup \halign #-0.2 \column {
     \right-align "D.S. al Fine" \right-align "e poi"
    }
  }
  \MusicRi
}

another_test = {
  R1
  \MusicRi
  R1*2
  \MusicRi
}

\score {
  <<
    \new Staff \testing_this
    \new Staff \another_test
  >>
}
%%%  SNIPPET ENDS

Hmmm… It would be nice to hear from others about whether this construction 
makes sense, is "safe", etc.
Certainly the ability to define variables "in-line" would be a bit of a 
game-changer for my Lily-coding.

Thanks!
Kieren.
