Clone the extended-categories package from https://github.com/ian-mi /extended-categories and checkout tag `0.2.0`. 2. Install the dependencies `tagged` and `constraints` into a sandbox if not already available. 3. Download the attached `Bug9574.hs` file. 3. Using GHC 7.8.3, load extended-categories into ghci using `cabal repl` and then load `Bug9574.hs`. Please let me know if you need any additional information.
