Comment #3 on issue 1999 by [email protected]: Nonsensical example in
programming-interface.itely
http://code.google.com/p/lilypond/issues/detail?id=1999
Inline Scheme does not access surrounding music.
Anyway, in the meantime the original example has become quite sillier since
the "problem case" works without even requiring the rather simplistic
modification given in the issue description.
Finding examples at tutorial level where one needs to revert to Scheme is
becoming harder. Nice for users, bad for tutorial writers.
