Neither GUILE nor MIT-Scheme are documented to allow this form of optional parameters (actually, both disallow it explicitly in the docs). Wouldn't it be better to re-write the code to #(define toplevel-book-handler (lambda rest (set! output-empty-score-list #f) (apply print-book-with-defaults rest))) (i.e. name the whole parameter expression rest instead of ( . rest ) and pass that on)? I've not tested this, though, so I might be completely wrong, but from the GUILE doc it seems that this does exactly the same as the undocumented ( . rest) and is documented to work.
