deriving-compat: Backports of GHC deriving extensions
Provides Template Haskell functions that mimic deriving extensions that were introduced or modified in recent versions of GHC. Currently, the following extensions are covered:
The following changes have been backported:
In GHC 8.0,
DeriveFoldablewas changed to allow folding over data types with existential constraints.
In GHC 8.0,
DeriveTraversablewere changed so as not to generate superfluous
pureexpressions in generated code. As a result, this allows deriving
Traversableinstances for datatypes with unlifted argument types.
Note that some recent GHC extensions are not covered by this package:
DeriveGeneric, which was introducted in GHC 7.2 for deriving
Genericinstances, and modified in GHC 7.6 to allow derivation of
Generic(1)using Template Haskell.
DeriveLift, which was introduced in GHC 8.0 for deriving
Liftusing Template Haskell.
