../@key doesn't work to get the index of a parent loop.

Syntax:

{{?><View>}}

example

class MyView extends View {
  name: string = 'myview'
  template: 'MyView: <input value::{{value}} oninput::{{oninput}}>'
  _value: string
  
  get value() { return this._vaule }
  set value(newValue) { this._vaule = newValue; this.render(); }

  @selfBoundEventSource
  oninput(evt) {
    let input = evt.target

    this.value = input.value;
  }
}

let myView = new MyView()

{{?>myView}}

2 + 3 * 4 = 14 but should be 20

With a simple object: { a: new Date() }, I get this error locally:

Uncaught Error: Unexpected virtual child passed to h().
Expected a VNode / Vthunk / VWidget / string but:
got:
"2017-02-03T01:56:36.792Z".
The parent vnode is:
{
    "tagName": "P",
    "properties": {
        "attributes": {}
    }
}

Using { a: 'a string' }, I get:

Uncaught TypeError: Expected 'object' but instead found 'string'
    at Object.assertTypeError
    at new Context
    at Context.newContext
...

Any ideas?

When an element is removed from an array, the _update() logic is flawed. I think we're going to have to somehow keep track if each element in the array has changed and do some magical redrawing.

Logic is at Bars/lib/frag.js#L310.

Something like {{@last(events)/id}} would be neat.

{{@some()}}

throws:

Uncaught TypeError: Cannot read property '0' of null
