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

there is nothing wrong with ifs as such except the won't actually exit a
long piece of code, the computation will continue, just in a useless way.
Primarily for every "if" I need two forks, so at every "if" the branches
I have written the previous code with ifs and it's quite spaghetti-ish
and I hope that using callCC here helps to avoid it.
Of course there is no guarantee that it actually will. ;)
