lookupIndex :: forall (m :: Type -> Type) . Int -> GVal m -> Maybe (GVal m)ginger Text.Ginger.GVal Treat a GVal as a flat list and look up a value by integer index. If the value is not a List, or if the index exceeds the list length, return Nothing.
lookupIndexMay :: forall (m :: Type -> Type) . Maybe Int -> GVal m -> Maybe (GVal m)ginger Text.Ginger.GVal Helper function; look up a value by an integer index when the index may or may not be available. If no index is given, return Nothing.
lookupKey :: forall (m :: Type -> Type) . Text -> GVal m -> Maybe (GVal m)ginger Text.Ginger.GVal Strictly-typed lookup: treat value as a dictionary-like object and look up the value at a given key.
