[Haskell-cafe] Re: Why?

Most of the discussion centers on the benefits of functional programming and laziness. Haskell is not merely a lazy functional language. It is a pure lazy functional language. I may need to explain what laziness is. Laziness is where you work through the logic in its entirely before acting on the result. In strict evaluation the logic is worked out in parallel with execution which doesn't make complete sense, but it does allow for an architecture that is close to the machine.
