Hi Gary,
This question is more suited to [EMAIL PROTECTED] instead of

That's exactly what's happening. It's a misfeature in my opinion, but it
makes it easy to iterate thru a dictionary .items() and a folder
.objectItems().

No, you're not, the feature is wrong :-)

The workaround is to make each tuple of your sequence the second
elemento of a 2-tuple, as in '((1, (1,)), (2, (1, 2)), (3, (4, 5, 6)),
(4, (4, 5, 6)))'
Kind of like that old joke were the paranoid statician would take a bomb
with himself to the plane because the odds of there being two bombs on a
plane were so low...
