A possibility to define variables (in proper LilyPond syntax) inside of 
\book or \bookpart environments would be really great to have, in order 
to simplify working with large projects, many includes and different 
target editions. I don’t think that not having a proper scope for each 
book/bookpart is a problem. So I’d vote for this change.
