[Haskell-cafe] Re: File handles and pipes

Pipes are perhaps a bit misnamed: if you want to combine the output of two pipes and funnel it into a third you can't simply "plumb them together", you need to provide code which reads from the output pipes and writes into the input pipe.

With the new System.Process in 6.10, that's not the case. If you're building a pipeline "a | b | c | d" you only need to write into "a" and read from "d", System.Process handles everything in between.
