For example, Object.getOwnPropertyDescriptor(object.aSignal, "connect") returns undefined, but object.aSignal.hasOwnProperty("connect") returns true and object.aSignal.connect is indeed a function. Similarly, Object.getOwnPropertyNames(object.aSignal) returns an empty list, even though the signal has properties connect, disconnect, length and name.
