I was leaning towards getting rid of metaclasses. A class reference like "String" would instead reference the String prototype, and class methods would be moved to instance methods under an appropriate category like "instance creation". Class variables can be replaced by instance methods that store arbitrary constants, instead of just literals. This allows overriding without the need to use class instance variables. And the prototype can serve as an example (enhancing documentation) or as a real prototype to copy. The prototype (or any instance) would respond to #new the same as today by creating a brand new instance. It would respond to #copy by copying itself. So the user has a choice.
