How can I tell JSDoc about the structure of an object that is returned. I have found the @return {{field1: type, field2: type, ...}} description syntax and tried it:

/**

 * Returns a coordinate from a given mouse or touch event

 * @param  {TouchEvent|MouseEvent|jQuery.Event} e    

 *         A valid mouse or touch event or a jQuery event wrapping such an

 *         event. 

 * @param  {string} [type=page]

 *         A string representing the type of location that should be

 *         returned. Can be either page, client or screen.

 * @return {{x: Number, y: Number}} 

 *         The location of the event

 */

var getEventLocation = function(e, type) {

    ...



    return {x: xLocation, y: yLocation};

}

While this parses successfully, the resulting documentation simply states:

Returns: 

    The location of an event

    Type: Object

I am developing an API and need people to know about the object that they will get returned. Is this possible in JSDoc? I am using JSDoc3.3.0-beta1.
