I think this relates to my preference of relative mode and Dutch note 
names. In contrary to the absolute mode and Do-re-mi-names, there is 
nearly no need to repeat single notes with q, since you can just type 
the note name another time without too much overhead (well, assuming you 
don't write too many eseses or fancy micro-accidentals).

I have to admit I had to look up \rest; I did not remember this command, 
and never used it so far. In such a case it really makes sense to have a 
shortcut for the copying, but IMHO the memoization of "simple rests" is 
unnecessary. May it be a reasonable decision to remember rests only if 
they have an attached pitch?

As another idea, I thought about implementing a custom copy policy for 
myself, which also copies some articulations, eventually those types 
defined by the user in a dedicated list. This could be done in Scheme: 
replace the repetition function and plug it in at runtime.
It'd be great if a similar approach could also be done concerning 
copying of simple notes vs. chords: The more you write in relative mode 
and with "simple" keys, the less you probably want q to memoize.

I'm not sure, though, if such a policy-based version is possible via 
Scheme (read: at runtime), since it seems to affect the parser.
