you have to ensure that the elements of the list are evaluated. Look at the different output from: #(let* ((A 0) (B 1)) (display `((,A ,B)(,B ,B)(,A ,A)))) #(let* ((A 0) (B 1)) (display '((A B)(B B)(A A)))) David explained this recently far better than I could, can't find it at the moment, though, > > 2. Setting connect to #t gives this GUILE error (this seems like a bug): > Wrong type argument in position 1 (expecting empty list): closepath No idea with this.
