\ is like lambda:

Perhaps it was chosen to look like the mathematical expression:
\
 \
/ \a b c.a+b+c

Haskell has a lot of nifty features and very nice syntax. Have anyone 
written a comparison?
Here is the original problem solved in Haskell anyway:

list1 = [ 1,2,3,4,5,6 ]
list2 = [ 6,5,4,3,2,1 ]

zipWith (-) list1 list2

(well, if you want print it nicely, you probably need
putStr (unlines (map show (zipWith (-) list1 list2)))
instead)
