I've looked at the docs again and think they're fine.  And in the 3.x docs, the iterator version of zip() specifies its implementation with a pure python equivalent that makes it clear that the iterator is not run to exhaustion.  

Note that zip() has existed since 2.0 and iterators/generators since 2.2.  The docs for them have worked just fine, so I wouldn't worry too much about their being a "trap for 99% of programmers who aren't implementers."

GPK, I can see that you're wound-up about this, but you seem to have a profound misunderstanding about iterators/generators and have incorrectly assumed an implied contract for consumer functions to completely consume their inputs.  Sorry, but I'm going to close this one.  For further discussion, I recommend the python tutor mailing list.
