[Haskell-cafe] QuickCheck-like tests with GHC.Generic deriving

[lucas di cioccio]

Hi

I have seen that SmallCheck's Serial class has Generic defaults, but it

> populate deeply nested data types, and SmallCheck's generator requires
> computing a few million values before I get any interesting ones)
>  Something "random" would be more useful for my purpose.

Maybe you can make your data instances of Random

http://hackage.haskell.org/package/random-1.0.0.2/docs/System-Random.html#t:Random

and
