You're referring to the freak result of Dan Doel?
Come on, be serious, please. I have a Haskell result that runs in 7ms, too.
Just use a rewrite rule and hey presto :)
Dan, why you have not said the same about test where ghc

to see whether any other ghc changes have helped in any way
- enable documentation of what exactly the issue is (why is it
