Certainly.  That there is a Function instance when the property is accessed 
does not need to mean that there is also a Function instance when it is not.  
It appears to be prudent that there is a getter that creates the Function 
instance and returns a reference to it not before the property is accessed, 
or there may be a factory that creates the Function instance when the event 
is dispatched to the element.

Insofar one should generally expect event-handler attributes to be more 
efficient than event-handler properties (and their correspondent API 
features) because with the latter the Function instance needs to be created 
first (by the developer).

What is the question?
