Why are you using zip in this case? If you *know* that you are going to
get back 1-tuples then you must know that the input is a single list
(i.e. you aren't using "apply"). So why are you using zip at all?

 Paul Prescod - Not encumbered by corporate consensus
Just how compassionate can a Republican get before he has to leave the 
GOP and join Vegans for Global Justice? ... One moment, George W. Bush
is holding a get-to-know-you meeting with a bunch of gay Republicans.
The next he is holding forth on education or the environment ... It is
enough to make a red-blooded conservative choke on his spotted-owl
drumstick.     - April 29th, Economist
