Re: Snippet 960 fails with Ly 2.25

Hi Harm, hi Aaron,

thanks a million for your immediate help. Good to know that this will
continue working in 2.25.

Aaron, I don't entirely agree that this is obsolete... it shows a
mechanism that can be further expanded. It is also the base for
https://lsr.di.unimi.it/LSR/Item?id=1000
and (even further developped)
https://github.com/openlilylib/analysis/wiki/Frames

I'll see what I can do to update those in a similar manner.

Cheers,
Klaus
