I doesn't seems to be easy, either with deepseq-th or deepseq-generic...
With deepseq-generic, the derivation of Generic doesn't work because I'm
using a GATD.
It says *"NewVar must be a vanilla data constructor"*.
For deepseq-th, I have this error:
*deriveNFData: 'forall' not supported in constructor declaration*
I have some complex data constructor...
So it looks like both deepseq-th and deepseq-generic are out of the game :((

You can (probably) automatically derive it via Template Haskell using the deepseq-th package:
{-# LANGUAGE TemplateHaskell #-} import Control.DeepSeq.TH
data MyState = ...
$(deriveNFData ''MyState)
In most cases where you think
You should probably try the deepseq-generics package before you try deepseq-th.
The generics version was suggested to me by the author of the TH version, Herbert Valerio Riedel. It seems to be just as fast as the TH version and doesn't require TH.
