I'd prefer not having such shortcuts in the API. As a parallel, see the W3C
File API's FileList interface

To read the size of a file you'd have to do:
    var size = document.forms['uploadData']['fileChooser'].files[0].size;
but that hasn't resulted in a shorter version like
    var size = document.forms['uploadData']['fileChooser'].size;

If developers are accessing "item[0].utterance" more than once in their
code they'd usually do
  var item = event.result.item[0];
  .. = item.utterance
