Comment #8 on issue 2003 by address@hidden: Patch: Implement \once as music  
function able to operate on complex stuff.
http://code.google.com/p/lilypond/issues/detail?id=2003

Been on countdown now for more than 2 days, blocking another issue, in  
spite of a GLISS-related discussion on that issue, no comment has been made  
in that respect on this patch, it does not add new user-level  
functions/keywords but "merely" extends an existing one.

Adam, regarding issue 2002 in the aspect of actually introducing a new  
keyword: I would oppose that in a discussion, and Graham would currently  
even oppose a discussion.  But personally I'd very much appreciate it if  
you turned your patch in the discussed manner into a documentation how a  
user might create \hideNote himself.  And if you still feel, once the time  
for discussing new user interfaces to existing functionality is open again,  
that a predefined command is warranted, feel free to bring it up again.   
You won't likely get my vote (once I have made my mind it is hard to turn  
around), but you might persuade enough others.
