Indeed it does, thank you.  And no, my Scheme would _not_ have been up to that. 
 I was still trying to figure out how to access the value of line-width, or 
indeed any of the \paper variables: the documentation is very clear on how to 
set them in the \paper block, but completely unforthcoming on how to get them 
from anywhere else.

In fact, even given your solution I'm not convinced I understand how it works: 
as far as I can see you have defined an anonymous function, but not actually 
evaluated it ... (I've been coding on and off for 30 years in a succession of 
Basic, Fortran, C, Matlab, C++, Python and even the odd spot of assembler, but 
Scheme remains quite impenetrable to me).

Best wishes,
