"Lazy and Eager Collections” is confused

- streamline the code - emphasize that this is an example of a way of thinking - reference the way Ruby has a module for iterations

e.g. ``` javascript const mapIterableWith = function * (fn, iterable) { for (const element of iterable) { yield fn(element); } }; ```

Probably warrants an explanation of the difference in semantics.

Iterators you own and don’t own.

All of the headaches that go with manually freeing resources.

If you could _create_ classes that are compatible with CoffeeScript, YouAreDaChef would be very useful for pure JS programmers.

Class-like things (Dots? Annotations?) that replace direct class manipulation. Serve as a signal of manipulations to come and permit retroactive manipulation (annotating a class should check for maniplations).
