Functional programming, immutability and the World.

In C++  if you write a cooking_meat() function it returns NOT a new piece of meat, but one with a changed state.

In Clojure we have:

• immutability - so we get here a NEW piece of meat

In real life it'd be not a wholly new piece of meat!

• world -> constantly changing state, we cannot understand all of the Change
• thus -> functional programming - our unability to cope with Change, to understand the world we are living in?
