Re: [Haskell-cafe] Re: Why?

2009/12/10 John D. Earle :

My intuition says that laziness and purity are distinct whereas yours says that purity is a necessary condition. This is what needs to be reconciled.

Mixing impurity and laziness makes code whose behavior is too hard to understand. So, there is no theoretical reason not to mix them, but there is a practical one.

I believe that everyone is thinking that lazy evaluation and strict evaluation are similar activities whereas they are profoundly different. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
