I very much like the lazy O in lazy IO, e.g. with this real-life code
hPutStrLn stderr $ "Out of " ++ show (IxS.size (binaries unstable `IxS.union` binaries testing)) ++ " binary packages, " ++ show (IxS.size unmod) ++ " are unmodified, but
" ++ show (IxS.size affected) ++ " are possibly affected."
Thanks to lazy IO, I get a very nice feedback about what the code is
doing right now, and how long the various values take to calculate.
