I've had trouble getting that to work in more complicated situations, such
as when there's nesting involved.  If I want a few notes different inside
\foo (for instance, because of needing to split them into separate voices
for typographical reasons while keeping them in a single voice for MIDI)
but then I want to either repeat \foo in a volta for print, or write out
the repeat to transpose one of them, then using the same tag for both
conditionals is a problem.  That can be worked around in turn by using
more tags, but the complexity steadily increases, and all of it is work I
think the computer should be doing, not the human.
