BTW, that thread is easier to follow on google: http://groups.google.com/group/comp.lang.python/browse_thread/thread/ca7ba6ca9d70d24c/fdcadd1e3eba61cd But googling shows I wasn't the first to come up with iter([]).next() to raise Stopiteration. Usual suspect: http://groups.google.com/group/comp.lang.python/browse_thread/thread/41495e4f5d3e1c2a/84c158ff18d08ece#84c158ff18d08ece It probably stuck subconsciously in my mind and just came back when I wanted a StopIteration expression for terminating a generator expression.
