New issue 1830 by [email protected]: \change only works with certain contexts
http://code.google.com/p/lilypond/issues/detail?id=1830
After realizing that a VerticalAxisGroup is created at the onset of certain
contexts, I asked myself: "what if these contexts were moved to another
context?" The code below does just that (in theory) and does not complain,
except that there is no change of PianoStaff.
<<
\new PianoStaff = "foo" <<
\new Staff { a' b' c' d' }
\new Staff { a' b' c' d' }
\new PianoStaff = "bar" <<
\new Staff { a' b' c' d' }
\new Staff { a' b' \change PianoStaff = "foo" c' d' }
It seems that some contexts should be marked as change-friendly and others
as not, and those that aren't should issue a warning when the
change-iterator comes a-knockin' on their door.
Cheers,
MS
