The standard ''Data.Bool'' module defines a ''bool'' function.
'''bool x y p''' evaluates to '''x''' when '''p''' is '''False''', and evaluates to '''y''' when '''p''' is '''True'''.
<lang haskell>import Data.Bool (bool)
main :: IO ()
main =
let raining = False
in putStrLn $ bool "No need" "UMBRELLA !" raining</lang>
{{Out}}
<pre>No need</pre>
