Comment(by jinmei):

 Replying to [ticket:410 vorner]:

 > I suggest that either the iterator returned should point to the first
 item or the documentation should equally clearly say that first() must be
 called before use.

 Hmm, I don't remember why I left the initialized position of the iterator
 cursor undefined, but I can't think of a reason why not now, and I'd agree
 it makes more sense to initialize it with the "first" position.
