derive-2.5.10: A program and library to derive instances for data types

Safe HaskellSafe-Infered



Derivation for the Typeable class, as described in the Scrap Your Boilerplate papers. This derivation generates instances for all kinds of TypeableK classes; as such we do NOT require the GHC-specific generic downkinding instances to provide lower kind instances.

Also creates a typename_<the type name> value to hold the TypeRep.
