group-by date

[danilovaz]

Is there any plan to allow group by date? The group-by only works with Strings. But there are many cases where you need to group by date, for example.

{{#each-in (group-by "date" sortedMessages) as |date sortedMessages|}}
  <h3>{{date}}</h3>
  <ul>
    {{#each sortedMessages as |chatMessage|}}
      <li>{{chatMessage.message}}</li>
    {{/each}}
  /ul>
{{/each-in}}
