{{yield}}

[Rich-Harris]

Once #4 is implemented, need to figure out a way to yield, without which component composition is somewhat limited:

{{#if error}}
  <Modal>
    <p>something went wrong!</p>
    <button on:click='set({ error: null })'>dismiss</button>
  </Modal>
{{/if}}

In Ractive that's done with the {{yield}} operator, and it works well. For simplicity's sake, probably best just to have a single yield per component (i.e. no named yields, and no yields in #each blocks) for now.
