Re: [Haskell-cafe] Using the ContT monads for early exits of IO ?

I would not use the continuation monad just for early exit. Sounds like the error monad to me. 2010/6/10 Günther Schmidt :

Hi everyone,

I'm about to write a rather lengthy piece of IO code. Depending on the results of some of the IO actions I'd like the computation to stop right there and then.

Now I know in general how to write this but I'm wondering if this is one of those occasions where I should make use of the Cont monad to make an early exit.
