Hi, I wrote a simple script for fannkuch redux. https://github.com/highfly22/fannkuch-redux/blob/master/fannkuch-redux.rkt
The result of this script is about 10 minutes in my i7 machine, which is better than Python, lua and ruby. Is the result expected? Do I miss something? I have tried to use unsafe op. That may reduces about 30 seconds. The optimizer couch complains the missed inline on the most time spent functions - flip and flip-count. I tried to re-write the functions to macros. But it doesn't change anything. I also tried to re-write in the typed/racket. It doesn't help either. Finally, I try to use future. There is not a blocking operation in the future-visualizer. But it's twice slow than normal version. Maybe task (each flip-count) is too trivial for this job. Thanks, Haiwei
