thank you for that name!!! It finally helped me figure out what the 
function was supposed to do.

now, documentation that included examples would be nearly as good...
select [1,2,3,4] = [(1,[2,3,4]), (2,[1,3,4]), (3,[1,2,4]), (4,[1,2,3])] 
--right?

or we could call it "howToAbductEachElement" ;-) but that belongs in the 
Haskell list library even less than "banishments"
