Using <code>map</code>:
<lang haskell>fs = map (\i _ -> i * i) [1 .. 10]</lang>
Using list comprehensions:
<lang haskell>fs = [const $ i * i | i <- [1 .. 10]]</lang>
Using infinite lists:
<lang haskell>fs = take 10 coFs where coFs = [const $ i * i | i <- [1 ..]]</lang>
Testing:
<lang haskell>> :t fs
fs :: [b -> Integer]
> map ($ ()) fs
[1,4,9,16,25,36,49,64,81,100]
> fs !! 9 $ ()
100
> fs !! 8 $ undefined
