Hi,

I am having a go with the new parsing API (just for learning purposes). How 
should I convert the following code ?

(avgTemp, avgHum) <- fold' averages (input >-> P.take 10)


https://github.com/PierreR/pipes-zmq3/blob/master/sub.hs#L66

Do I replace (input >-> P.take 10) with zoom (splitAt 10) drawAll ? Then 
how do I use the parser with Foldl ?

As a note, it seems to me that I don't need to check for stream termination 
with zeromq because I always get one message or nothing at all. The haskell 
zeromq lib takes care of dealing with error conditions already.
Is that right ?

Thanks for your help,

Cheers
