The new syb package has basically all the Data.Generics.* modules.
In base4, no Data.Generics.* modules were kept. Instead, a new module,
Data.Data, contains all that was in Data.Generics.Basics and most of
Therefore, in the syb package, Data.Generics.Basics only re-exports module
Data.Data from base4, and Data.Generics.Instances defines the instances
missing from Data.Data and re-exports the instances from Data.Data.
