A challenge for the Lilypond hacker gurus: Would it be possible to design a custom engraver/function/..., that triggers a warning if you typeset a score where some, but not all the parts have a repeat at the same spot?
As you may guess, I just found a missing repeat in one part of a piece I have typeset, where I had carefully proof read all the original parts against the LilyPond generated score, but hadn't proof read the individual parts.
Obviously, there are many situations where this warning wouldn't be desired, for example when you have different lyrics in the repeats, so it shouldn't be triggered by default. Still, it would be a nice feature to be able to activate from time to time.
