Ah, my mistake there, was thinking of (function(){}).constructor for a
moment there.

Thinking about it with the new keyword in mind, I just realise that
what Garrett suggested makes no sense anyway - the function object is
the constructor. The function object is an instance of Function, but
the resulting object is an instance of the function object. Making the
object have Function as it's constructor property breaks the
prototype-constructor relationship.

Sad to hear that, but I guess compatibility will have to rule here.
