Haskell point-free

I have this:


ops :: [[Char] -> [Char]]
...
fun :: [Char] -> [[Char]]
fun str = zipWith ($) ops $ words str

How do I write fun in a point-free style? Dropping the argument gives me type errors.

Function application has a higher precedence than any user-defined operator. Just remove the parens. Write sin x ^ 2, not (sin x) ^ 2. Also, please always use spaces around all binary operators, so that words . lines is consistent with Just . lines (since Just.lines means "the function lines in the module Just")
