From pro@…:

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.

Hi,

Is this a known bug? I don't have the expertise to describe the problem in a sensible way--I'm not even sure whether it has to do with 'do' per se--but you'll see what I mean. This is on: 1.6-r14468M (DarwinX8664)!

Line breaks added for readability:

? (setf (get 'sym1 'prop) '(this that theother))
(THIS THAT THEOTHER)
? (setf sym2 'sym1)
SYM1
? (do ((lst (symbol-plist 'sym1) (cdr lst))) 
      ((null lst) t) 
   (princ (car lst)))
PROP(THIS THAT THEOTHER)
T
? (do ((lst (symbol-plist sym2) (cdr lst))) 
      ((null lst) t) 
    (princ (car lst)))
;Compiler warnings :
;   In an anonymous lambda form at position 24: Undeclared free variable SYM2PROP(THIS THAT THEOTHER)
T
? 

Thank you for ccl, btw. It seems incredibly fast, which matters for my application.

Tracing CCL::%EXTEND-VECTOR-OUTPUT-STREAM shows many calls of the function,
and each call doubles size of :outbuf.
