programming error: bounds of this piece aren't breakable. I haven't
found a way to make it work with single-note slurs at the beginning of
the line.
* It works for lyric hyphens and extenders if there's an extra note
with no lyric to extend to. I have to use as the lyric for this
note, not _. This has the side effect that the lyric syllable isn't
aligned properly at the end of the line (it's centered under the note
instead of left-aligned).
* I can't get it to work for ties in either direction no matter what I try.
* It doesn't do anything to explicit beams (not that I suppose anyone
would want to break beams this way), and it doesn't work properly with
ligature brackets or tuplet brackets -- the bracket extends to the bar
line but appears to begin/end there instead of being broken.
MS, I hope you can tell me if there's a way to work around these
problems in Scheme alone.

Greetings, Ben Rudiak-Gould -
I was hoping someone else would respond, but I haven't seen anything, so
here goes . . .
I know almost nothing about Scheme, so I won't try to evaluate your
snippet. However, the function would be valuable, so I would encourage you
to submit your snippet to the Snippet Repository so that others can use it.
Do you want to make this a feature request?
All the best,

In theory all of this is hackable via Scheme. What you'd wanna do is create custom engravers for both lyric extenders and ties. The engravers would attach these Spanners to the targeted note as well as the next or previous NonMusicalPaperColumn (and broken variants thereof). By attach I mean use them as left and right bounds. The rest should take care of itself - LilyPond already knows how to engrave most spanners between a NonMusicalPaperColumn and a note.

Mike, Ben, do you want a tracker for this? Are you going to design a custom engraver, Ben, using Mike's suggestion above, and try it out on your score first? Give me a title for the tracker that makes sense to you. I think perhaps Allow for non-continuing broken spanners. What would be awesome is to find a generic way to implement this for all spanners.
