curly brackets in data binding delimiters not supported

[andrelanger]

It seems currently not possible to access array content within a data binding expression.
Example:

<dom-module id="x-weather">
 <template>
    {{weather.main.temp}}°C, {{weather.weather[0].description}}
    <iron-ajax
     auto
     url="http://api.openweathermap.org/data/2.5/weather" 
     last-response="{{weather}}">
    </iron-ajax>
  </template>

  <!-- ... -->

</dom-module>

The example results in the following output:

20°C weather.weather[0].description

I am not sure if it is similar and related to #3527

You actually have to use .0 instead of [0]. A working example: http://jsbin.com/wogurat/edit?html,output For more info see https://www.polymer-project.org/2.0/docs/devguide/data-binding#array-binding
