Discussion
If you named your function DeleteProperty, you would declare it like this:
bool DeleteProperty(JSContextRef ctx, JSObjectRef object, JSStringRef propertyName, JSValueRef* exception);
If this function returns false, the delete request forwards to object's statically declared properties, then its parent class chain (which includes the default object class).
