1. data TypeFamilyHead

   template-haskell	Language.Haskell.TH

   Common elements of OpenTypeFamilyD and ClosedTypeFamilyD. By analogy with "head" for type classes and type class instances as defined in Type classes: an exploration of the design space, the TypeFamilyHead is defined to be the elements of the declaration between type family and where.

2. TypeFamilyHead :: Name -> [TyVarBndr BndrVis] -> FamilyResultSig -> Maybe InjectivityAnn -> TypeFamilyHead

   template-haskell	Language.Haskell.TH

   No documentation available.

3. ppr_tf_head :: TypeFamilyHead -> Doc

   template-haskell	Language.Haskell.TH.Ppr

   No documentation available.

4. data TypeFamilyHead

   template-haskell	Language.Haskell.TH.Syntax

   Common elements of OpenTypeFamilyD and ClosedTypeFamilyD. By analogy with "head" for type classes and type class instances as defined in Type classes: an exploration of the design space, the TypeFamilyHead is defined to be the elements of the declaration between type family and where.

5. TypeFamilyHead :: Name -> [TyVarBndr BndrVis] -> FamilyResultSig -> Maybe InjectivityAnn -> TypeFamilyHead

   template-haskell	Language.Haskell.TH.Syntax

6. lookAhead :: Get a -> Get a

   binary	Data.Binary.Get

   Run the given decoder, but without consuming its input. If the given decoder fails, then so will this function.

7. lookAheadE :: Get (Either a b) -> Get (Either a b)

   binary	Data.Binary.Get

   Run the given decoder, and only consume its input if it returns Right. If Left is returned, the input will be unconsumed. If the given decoder fails, then so will this function.

8. lookAheadM :: Get (Maybe a) -> Get (Maybe a)

   binary	Data.Binary.Get

   Run the given decoder, and only consume its input if it returns Just. If Nothing is returned, the input will be unconsumed. If the given decoder fails, then so will this function.

9. lookAhead :: Get a -> Get a

   binary	Data.Binary.Get.Internal

   Run the given decoder, but without consuming its input. If the given decoder fails, then so will this function.

10. lookAheadE :: Get (Either a b) -> Get (Either a b)

    binary	Data.Binary.Get.Internal

    Run the given decoder, and only consume its input if it returns Right. If Left is returned, the input will be unconsumed. If the given decoder fails, then so will this function.
