Re: [Haskell-cafe] Derving NFData via Generics from a type that has a vector doesn't work. (was trying to understand out of memory exceptions)

17 Apr 2013

      so this one works

instance NFData (V.Vector a) where rnf a = force a `seq` ()

any reason why something like this isn't part of the vector library?

Thanks,
Anatoly

Thanks,  So now i at least get a compiler error
No instance for (NFData (V.Vector Double))
So how would one define NFData instance for vector?
