What does it mean "close to math"? How close? Does math raise exceptions upon the division by zero? Does *MATH* answer the question what is: (0/0)==(0/0) ? Nope!
Exactly. So why try to give an answer in Haskell? MATH says: the expression 0/0 is undefined, thus comparing (0/0)==(0/0) is undefined, too. I would expect Haskell to say the same. Cheers Ben
