I just pushed a new version of
p0.hs to the website that loads under my GHCI installation. The problem seems to be related to the QuickCheck libraries that are not used for this project. I have vague memories of issues with Parsec libraries as well, but those load fine for me. If you are having issues with the new
p0.hs file loading, please let me know asap and I’ll look further into the issue.
I suspect that if you do a full Haskell Platform installation that includes all the libraries, this problem will go away. I have not tried this, so no guarantees. Hopefully I’ll get a chance to try it before class tomorrow.
