Yes, make sense like that. I'm not sure what to do about the iterator when is on an invalid item, if y= ou=20 reach an invalid item doing to_next should be possible to do to_previous to= =20 recover the last valid item? Or is better to force the user to use to_last = to=20 go back? In some cases implement to_previous will need to store the previous item=20 (actually I did that on the patches I sent). --=20 Rub=E9n Poll=E1n | jabber:meskio@jabber.org -=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-=3D-= =3D-=3D-=3D-=3D-=3D- =C9sta es la historia de una sociedad que se hunde y mientras cae se repite: hasta ahora todo va bien, hasta ahora todo va bien ...
