It's apparently not very SEO'd. But it's a debugging technique. http://coreygoldberg.blogspot.com/2008/12/wolf-fence-debugging.html http://coreygoldberg.blogspot.com/2008/12/wolf-fence-debuggi... It's universally applicable. I've done it in C, Scala, Go, Java, Haskell..everything. Perf-debugging wise - you basically remove parts of your computation and perform binary search to hone in on the parts that are on the critical path. I agree that a lot of Haskellers come off as "what's the problem?" (including myself). But Haskell is a small, niche, weird language. You kinda need that attitude to dive deep into it.
