why in the world would you write a summation function like that?
gui/db libs are imperative ones and using them you need to deal with a lot of mutable values. this example shows that programming with mutable data is less better done in C than in Haskell - imperative language has a lot of syntax sugar which allows automatic generation of all those readIORef/writeIORef calls (or their equivalents) -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
