Could you explain what the function does.. I can't seem to peice it
together.
It takes three things 1) a function 2) an index and 3) a list. It
finds the nth element of the list, applies the function to it and
then returns a new list containing the new element in the same
position. It dies with an error message if you index past the end of
the list.
e.g.
updateList (\x -> x + 10) 3 [0,1,2,3,4,5] == [0,1,2,13,4,5]
