1. I should have quoted Mike Meyer's code "if len(s) == 1: res =
process(next(iter(s)))", which is what I had in mind. (In that case,
it's a feature. :) )

2. I grouped it this way as a joke. If you do this, everyone will
think you're crazy. I've been known to write it (item,) = s, which
makes it a little easier to see the comma.

If you want to be unambiguous AND confuse everyone, go with

>>> s
set([42])
>>> [item] = s
>>> item
42
