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

[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.
