[Haskell-cafe] CIS 194 not compiling under new GHC

Hi all, I've been working through the CIS 194 https://www.cis.upenn.edu/~cis1940/spring13/lectures.html course recently and unfortunately from lecture 7 onwards the code is not compliant with current compiler. I can still follow the lectures but I'd like to do every homework exercise. Unfortunately most homework exercises provide you with a code framework to work with and this code does not compile. Do any of you know about updated versions or corrections to this course? I believe there could be a repo where someone is keeping the course's homework up to date because this course is still quite popular. Regards Borys
