Why do you have to use cadr and not cdr on the ly:grob-set-property
line? Isn't the broken part the second item in a list of two items? How
to understand this?
In Scheme, a list is a pair, containing the head/car (first element of
the list) and tail/cdr (sublist of all other elements). A list
containing only one element is a pair of that element and an empty list '().
'(1 2 3 4 5)
is the same as
'(1 . (2 . (3 . (4 . (5 . ()))))
So the car of the list above is 1, the cdr is '(2 3 4 5). If you want to
get the 2, you have to take the car of '(2 3 4 5). And cadr is short for
“car of cdr”.
