Cannot use object destructuring with custom variables in v-for

[preaction]

When I try to use ES2015 object destructuring with custom variable names (to map the data property to the player value), I get the following error message:

ERROR in ./~/vue-loader/lib/template-compiler?{"id":"data-v-6489d922"}!./~/vue-loader/lib/selector.js?type=template&index=0!./src/components/player-list.vue

You may need an appropriate loader to handle this file type.

The template I'm using is:

<template v-for="{ data: player, index } in sorted( players )">
  <tr>
    <td>{{ index }}</td>
    <td>{{ player.name }}</td>
    <td>{{ player.dci }}</td>
  </tr>
</template>

The sorted method returns an array of objects like { data: <object>, index: <int> }, and I want to map the data field into a descriptive name (since it's a Player object).

This syntax seems to work fine without vue-loader: http://jsfiddle.net/0ynef4b4/2/

Thanks for the quick turnaround!
