[Haskell-cafe] On the verge of ... giving up!

Cool! Lots of opinion. Let me consider them one by one:

I tried this too, and this made some sense to me in the beginning. But,
not enough to satisfy my curiosity! So, I tried to dig in ...

IO isnt the only problem. Monads + how to define your own Monads etc.
Since Monad's arent just for IO, where else could it be used? (e.g.
Stateful functions), but is that it? Is it possible for me to come
up with an instance of a Monad to solve _my_ problem? Thats the kind
of question I would like to answer :)

You are probably right. Mimicking *nix tools might be great fun to start
off with :)

Thanks :)
