Widget subclass abstraction

I'm working with one base widget that has a number of different sub-widgets and am having difficulty with abstraction. I would like to be able to call a function of a widget even if I don't know the widget's name. In other words, I want to be able to write this: $element.base_widget('myfunction');. Right now, that throws an exception because it's looking for an instance of the base widget and ignoring widgets that inherit from the base widget.

  // define two widgets, one as a subclass of the other:
  $.widget('', { identify: function() { return 'bar'; } });
  $.widget('foo.baz', $, { identify: function() { return 'baz'; } });

  $a = $('<a />');
  // => returns 'baz'
  // => expected: return 'baz'
  // => actual: throws exception: Error: cannot call methods on foo prior to initialization; attempted to call method 'identify'

There's no sane way to handle this. See for a related discussion.
