[0.9.0-rc.1] Method expression without arguments is not invoked

[GabiAxel]

For methods defined like this:

Polymer(
   is: 'something-something',
   method: function() {
      return "something";
   }
);

The following works:

[[method(someObject)]]

But this does not work - the method is not invoked at all:

[[method()]]

Can confirm. It seems like this is also failing if more than one argument is passed in, as can be seen in PolymerElements/paper-drawer-panel.
