I've read 
http://lilypond.org/doc/v2.19/Documentation/extending/lilypond-scheme-syntax 
(as no doubt, Urs has) and tried to use $ in place of #.  Can't get it to 
compile.  So, taking the following note doubler, how would $ be used instead 
of #?

dubble = #(define-music-function( parser location arg )
 (ly:music?)
 #{ $arg $arg #}
)

{ c'' \dubble c' }
