Get the item in the current position.
This method retrieves the item in the current position. It’s the user’s responsibility
to know what is the correct type of the item and give it while calling this method.
Since the item in the lists are stored in a serialized way the returned object
is not a reference to the item stored in a DB but actually a new instance of it.
The method returns Some(V) if deserialization succeeds or None otherwise.
