Note that it is not always possible to separate IO from pure code. As an example, consider an HTTP 1.1 server that read a request body containing a number for each line, and return a response body containing the sum of the numbers. Here, you can not really separate IO from pure computation. And you can not use lazy IO, if you want your server to support HTTP 1.1 pipelining.
I have done exactly this, but I needed to define the LazyIO type: http://hackage.haskell.org/cgi-bin/hackage-scripts/package/http-monad http://hackage.haskell.org/cgi-bin/hackage-scripts/package/lazyio _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
