Oh really? Haskell is not suitable for practical use? Try getting any software firm to adopt it and explain to them how I/O works with monads and about applicative functors. You will be met with resistance every step of the way.

I love Haskell and use it nearly every day to do mathematics and a number of side projects. Please step off your high horse and throwing all this ad hominem around. You're giving haskellers a bad name everywhere.
