1. firstJusts :: Foldable f => f (Maybe a) -> Maybe a

   ghc-lib-parser	GHC.Data.Maybe

   Takes a list of Maybes and returns the first Just if there is one, or Nothing otherwise.

2. firstJustsM :: (Monad m, Foldable f) => f (m (Maybe a)) -> m (Maybe a)

   ghc-lib-parser	GHC.Data.Maybe

   Takes computations returnings Maybes; tries each one in order. The first one to return a Just wins. Returns Nothing if all computations return Nothing.

3. first_code :: GenStackFrame b -> !b

   ghc-lib-parser	GHC.Exts.Heap.Closures

   No documentation available.

4. fIRST_TAG :: ConTag

   ghc-lib-parser	GHC.Types.Basic

   Tags are allocated from here for real constructors or for superclass selectors

5. firstDataDefnCon :: DataDefnCons a -> Maybe a

   ghc-lib-parser	Language.Haskell.Syntax.Decls

   Retrieve the first data constructor in a DataDefnCons (if one exists).

6. first' :: Strong p => p i a b -> p i (a, c) (b, c)

   indexed-profunctors	Data.Profunctor.Indexed

   No documentation available.

7. firstMap :: forall d (f :: Type -> Type -> Type) a b . (DFunctor d, Bifunctor f) => (a -> b) -> d (f a) -> d (f b)

   yaya	Yaya.Functor

   This isn’t a Functor instance because of the position of the a, but you can use it like: > newtype List a = List (Mu (XNor a)) > instance Functor List where > fmap f (List mu) = List (firstMap f mu)

8. firstValueE :: IsSql2003FirstValueAndLastValueExpressionSyntax agg => agg -> agg

   beam-core	Database.Beam.Backend.SQL.SQL2003

   No documentation available.

9. firstValue_ :: (BeamSqlBackend be, BeamSqlT616Backend be) => QExpr be s a -> QAgg be s a

   beam-core	Database.Beam.Query

   No documentation available.

10. firstSerial :: Serial

    dbus	DBus

    Get the first serial in the sequence.
