If you do a student's homework, you are cheating that student out of an education.
Personally, I tend to find "exercises" without access to the answers a poor way to learn. You'll learn more from a well crafted example than you ever will by struggling at something yourself.
In these lines, the homework policy could be extended to contain great solutions to all typical homework tasks. Teachers could build on that by instructing students to study and use such solutions to solve other tasks. Bonus could be given to students who could find even better solutions than those in the page, maybe with exponencial prizes like Knuth's checks :) Best, Maurício _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
