Funny. I thought he was talking about Java 8 for a while. We (eventually, when the rest of the stack catches up) get functors / lambdas, but:
* red = instance methods.
* blue = static methods, which cannot call an instance method.
* red = instance methods.
* blue = static methods, which cannot call an instance method.
Once you go functional, instance methods start to look like a special klugery for currying the first argument to a function. Go and Nim (for instance) hint at this more than a little, as well, with their OOP syntax.
Bundling two kinds of methods within a "class" starts to feel weird when you start using individual functions.
