Re: Data.Ratio and exceptions

Hello Henning,

I know people get annoyed quickly if I start a new round of "errors vs. exceptions" ...

Would you explain how they get annoyed concretely?

In Haskell there is only one undefined value and that should be equivalent to an infinite loop. Every distinction between 'error', 'undefined', infinite loop, DivideByZero is only for debugging purposes. Don't rely on being able to catch them! The only correct way to cope with division by zero is to not let it happen.

Let's define a new constructor of ArithException for debugging purposes. --Kazu
