Again, any pointers are much appreciated.
Well, sure. (100 . 50) is not a Scheme expression you could evaluate. You'd have to write #(set-default-paper-size ''(100 . 50)) instead since you then need one quote level more. Alternatively you could call eval only when given a list or a symbol and just retain what you got otherwise. That may lead to somewhat inconsistent behavior. -- David Kastrup
