I'm fairly sure that what I did after copying in the function was switch to an import; my ultimate fix was easy and irrelevant. This was a long time ago, and what made it stand out in my mind was my horror at discovering for a trivial 2-liner, all of GHC was being depended upon. -- gwern _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
