Out of scope, alas. One of the real challenges of the book was deciding which language features to include and which to omit. It's on track to an enormous book — it's over 200k words already. So I had to cut what I could. The language in the book doesn't even have arrays. But it does have lexical scope, closures, objects, inheritance, a full operator precedence table, and a bunch of other fun stuff.
