With a bit of work, we can define a ternary conditional operator in Haskell. Courtesy of Andrew Baumann. This appears only to be valid in Hugs?
import qualified Prelude data Cond a = a : a infixl 0 ? infixl 1 : (?) :: Prelude.Bool -> Cond a -> a Prelude.True ? (x : _) = x Prelude.False ? (_ : y) = y test = 1 Prelude.< 2 ? "yeah" : "no!"
