wg-runtime Status Update 2019-08-19

## What was accomplished

- Fix-it
  - Launch amp-script
  - `jsonConfiguration()`
  - amp-list: DOM diffing and error UI

## Lessons learned

- Code branching on const private props are not DCE’d 
```js
/** @const */
this.nope_ = false;

if (this.nope_) {
  foo(); // Still bundled.
}
```

## What's next

- amp-script + amp-state
