Ticket #866 (closed defect: invalid)
boa constructor supplied-p argument
|Reported by:||rme||Owned by:|
I tried to save a supplied-p parameter from a BOA constructor like this:
(defstruct (delayed-iseq (:constructor iseq (start-or-end &optional (end 0 end?) (by 1) strict-direction?))) "Delayed index sequence evaluation." start-or-end end end? by strict-direction?)
but SBCL complained that end? was not used. After rereading the CLHS page for defstruct, I am still not 100% sure why this is. My intepretation is that END? is an argument like any other, but probably I am not getting something.
