Custom Query (1030 matches)

Running the code in attached file, in which 10 threads cons hysterically, will pretty reliably elicit heap corruption.

From Matt Lamari, see ​http://clozure.com/pipermail/openmcl-devel/2011-May/012827.html.

For CASE forms with suitably small ranges of integer keys, the compiler could generate a jump table (or binary search, or a combination of the two) rather than the obvious linear search.

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.
