 I think I've captured the key features, but there are still things missing:
 
-* As of now, only functions with 8 or fewer parameters can be quickchecked.

 * Functions that fail because of a stack overflow are not caught by QuickCheck.
 Therefore, such failures will not have a witness attached
 to them. (I'd like to fix this, but I don't know how.)
