Assert that some value is Nothing.
nothing :: forall (m :: Type -> Type) a . Monad m => Predicate m (Maybe a)
skeletest Skeletest.Internal.Predicate Skeletest.Predicate
A predicate checking if the input is Nothing 
>>> Nothing `shouldSatisfy` P.nothing
nothing :: forall (l :: Type -> Type) . Prime l l
xmonad-contrib XMonad.Config.Prime
This doesn't modify the config in any way. It's just here for your initial config because Haskell doesn't allow empty do-blocks. Feel free to delete it once you've added other stuff.
nothing :: Pattern a
tidal Sound.Tidal.Boot, tidal-core Sound.Tidal.Pattern
nothing :: Expr
express Data.Express.Fixtures, code-conjure Conjure.Engine Conjure.Expr
Nothing bound to the Maybe Int type encoded as an Expr. This is an alias to nothingInt.
nothing :: Iso () (Maybe a)

Traversal on the Nothing element of a Maybe.
nothingActionGet :: (HasCallStack, MonadIO m) => m NothingAction
gi-gtk GI.Gtk.Objects.NothingAction
Gets the nothing action. This is an action that does nothing and where activating it always fails.
nothing_ :: SqlJustable a b => b
beam-core Database.Beam.Query
Return either a 'QExpr (Maybe x)' representing Nothing or a nullable Table or PrimaryKey filled with Nothing.
