Re: [Haskell-cafe] Simple way to do something like ArrowChoice.right on a Conduit? (version 1.0.0)

Can I transform a conduit so some values are passed through unchanged, but others go through the conduit? For example:

right :: Conduit i m o -> Conduit (Either x i) m (Either x o)

Actually, I didn't need this after all. I'm using Automaton from the arrows package for the first part of my pipeline. Only the zlib compression step is a Conduit, so I can just use arrow functions to lift Flush to the rest. Nonetheless, someone else might want to do this. Now that I think of it, not all of the arrow operations make sense (in particular, (***)), but splitting data between conduits (like ArrowChoice (+++)) does make sense, I think.
