[Haskell-cafe] Arrows and streaming/piping

[PY]

Hello, Cafe!

There is a statement that Arrows can be used as streaming approach. 
Arrows are very new for me, so my question may looks stupid, but would 
somebody show me clean and simple example how it will look? Lets suppose 
we have function `getLines` which returns `IO [String]`, a lot of lines 
:) And I want to process them as I do it with streaming library (or 
pipes) - with constant space.

If it's true, then I can use Arrows instead of pipes, right?
