I don't know how much overhead that means. My intuition says it's not 
that bad, since it does not at all affect the positioning and layout, 
which AFAIK takes the lion's share of LilyPond's runtime. But it's 
really just intuition...

I suppose when this shortcut is polished, it will become part of the 
basic syntax in no time, so it should be as easily accessible as 
possible. That's a different thing than, e.g., the #'keep-inside-line 
property of NonMusicalPaperColumn, since it affects whether a file will 
compile at all, not just how it looks like.
If we allow the user to override the semantics of q, we could as well 
forbid it's use before "booting" it up, though - it's very similar to 
the choice of input note names. A sensible default could also be the 
"don't copy anything and throw an error on use"-policy.

In any case, I'd rather not suggest an \include "..." syntax, 
considering the recent discussion about \include "language.ly" and the 
problem w.r.t. jail/safe mode.
