Hi, > + (assert-error (alist-ref 'foo 'bar cmp)) > + (assert-error (alist-ref 'foo '(bar) cmp))) What's a good predicate to use to check whether what will be passed to alist-ref will not throw an exception? The 2nd assert-error rules out a simple list? or an O(1) algorithm. (Tho' list? is already O(n)). Regards, @ndy -- address@hidden http://www.ashurst.eu.org/ 0x7EBA75FF
