[Simon, I must have missed that ghc-bugs is subscribers-only] There's an #ifdef'ed version in there which is stable, but the newer mergesort is not: #ifdef USE_REPORT_PRELUDE sort = sortBy compare sortBy cmp = foldr (insertBy cmp) [] #else sortBy cmp l = mergesort cmp l sort l = mergesort compare l {- Quicksort replaced by mergesort, 14/5/2002. nhc98 has a stable mergesort, I'm told.
