- From $ZOPE/lib/python/ZTUtils/Iterator:
Unlike the builtin iterators of Python 2.2+, these classes are
designed to maintain information about the state of an iteration.
The Iterator() function accepts either a sequence or a Python
iterator. The next() method fetches the next item, and returns
true if it succeeds.

Note that last sentence, which explains why you are seeing the '1' value
everywere. 'tal:repeat' over a range should get you what you want; I
don't think you *need* an iterator for your use case.
