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)

Hi again.

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

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

Quoting from the Changelog at http://hackage.haskell.org/package/vector : " Changes in version 0.10 * NFData instances " So it's there, and even in the current Haskell Platform. Cheers, Andres -- Andres Löh, Haskell Consultant Well-Typed LLP, http://www.well-typed.com
