Fixed the listiterator.next method to raise an exception instance.
Added a tuple.__iter__ implementation.
Removed "__init__" from the names_always_used list, introducing it into the
attribute coverage mechanism.
Fixed unknown name detection in the translation code.
Fixed an example where globals were used before being defined.
