I did not know about that shorthand — thank you! I always did this: (import (srfi srfi-9)) ; define-record-type (define-record-type <cat> (make-cat name age color) cat? (name cat-name) (age cat-age) (color cat-color)) Compared to that the syntactic form you showed is much nicer. Is there a difference in efficiency or such?
