Re: Produce a paper block from Scheme function

[Simon Albrecht]

Hi Urs,

I don’t quite see your problem. I’m using such functions without. Since 
multiple \paper blocks are combined in a rather sensible way, there’s no 
problem with just having the function output an entire \paper block and 
use it on top level, regardless of any other \paper blocks (except if 
they also use #(define fonts …)).
You didn’t say what’s actually supposed to be the argument of the 
function, but I attached an example.

HTH, Simon
