The file storage iterator was implemented before Python had iterators. (Actually, Python previously had an iterator based on a corner of the sequence protocol, which FileStorage used.)
There's a test for storage iterators that verifies that they raise a special exception that extends StopIteration and IndexError. This makes storage iterators a bit harder to implement than necessary. Does anyone know of a reason why we should have to raise a special error that raises IndexErrors?
