we get classes _and_ modules _and_ typed objects

There aren't "typed objects". There is a new library for working with binary data efficiently.

Classes and modules serve different purposes. Classes provide syntactic sugar for prototypal inheritance. Modules provide a baked-in mechanism for encapsulating and sharing code.

same with macros and codegens

Neither of these are on tap for ES6. Brendan showed them as interesting experiments that may be proposed for a future release.

Quite right about macros, but codegen is happening now, all over the place.
