A iterator with a generic method next()?

[Paulo Levi]

Recently i'm thinking that a iterator with a
<T> T next()  method is a good idea, for some uses. The interface is
different from the normal iterator, so it can't be used for
the for loop (or at least it would be fairly useless if so), but i'm
thinking of using it as a proxy of ObjectInputStream + factories in
case that the object in the file are not there (or the file doesn't
exist), where the saved objects are of different types.

Just tossing this idea into the melting pot.
