to be explicit, for example:
(define-record-type aaa (fields a))
(define-record-type bbb (parent aaa) (fields b))
(define r (make-bbb 1 2))
Then match it:
(($ bbb ($ aaa _ a) b) (list a b))
==> (1 2)
If you match it as ($ bbb a b), then a will be bound to the instance of
Could you provide you config file?
