I've been trying to get hat-trans to eat QuickCheck, without much success. Is there something I'm missing? I'm getting this error: hat-trans QuickCheck.hs head: `-1 ' option is obsolete; use `-n 1' since this will be removed in the future hat-trans: Variable or constructor not in scope: chr Any ideas? I know Neil got it to work, so I'm guessing brain fart on my part. Bob
