Then one could use make-engraver.

True, true.  My motivation here was to allow it to work with earlier versions.  It's just the example that won't, without modification.

Using define-event-class makes the file unfit for inclusion in
multi-file runs of LilyPond since define-event-class permanently changes
LilyPond.

I'm a little confused by the word "permanently".  Here I understand that the new event-class, measure-counter-event, will persist between the files if I run a group of files containing my file, but will be gone in a new session not involving that file.  Any problems which might result will only affect that multi-file run?

 

I am working on a replacement
<URL:http://code.google.com/p/lilypond/issues/detail?id=2449>, but the
pending patch is just one of several changes needed for changing the
event class hierarchy into a per-parser item instead of a global entity.

Thank you, David--I appreciate this very much.
