The Oscillator interface is already on the global object, since the  
(http://dev.w3.org/2006/webapi/WebIDL/#NoInterfaceObject) attribute isn't  
(and shouldn't be) used in the Web Audio API spec.

That being said, I have no real opinion about constructor shorthands,  
other than that it should be consistent -- either all properties are  
settable in all constructors, or none are.
