[Haskell-cafe] Conduit : is it possible to write this function?

Hi all Using the Conduit library is it possible to write the function: eitherSrc :: MonadResource m => Source m a -> Source m b -> Source m (Either a b) which combines two sources into new output source such that data being produced aysnchronously by the original two sources will be returned as either a Left or Right of tne new source? If so, how? Cheers, Erik -- ---------------------------------------------------------------------- Erik de Castro Lopo http://www.mega-nerd.com/
