Re: [Haskell-cafe] On the purity of Haskell

[Jerzy Karczmarczuk]

Iustin Pop::
In practice too:
bar _ = do
    s<- readFile "/tmp/x.txt"
    return (read s)

Once you're in a monad that has 'state', the return value doesn't
strictly depend anymore on the function arguments.
Nice example. PLEASE, show us the trace of its execution. Then, the 
discussion might be more fruitful
