Hi all, Is there a serialization library other than the Data.Binary from hackage?

Yes. "binary-strict" is one alternative: http://hackage.haskell.org/cgi-bin/hackage-scripts/package/binary-strict

I am using Data.Binary in a couple of projects, but I have found its stack and memory usage very hard to control. Its very common that decoding a map or list of non-trivial size uses up all available RAM, or causes a stack overflow.

I don't care that much about it being extremely fast, I just want to stop worrying that if I try to read a file a few percent larger than the last time, my program will suddenly stop working.

Best, -- Grzegorz

There are Iteratees[1]. They're still grok-in-process___ community-wise They are (afaik) currently only used for file input, though it's certainly possible to enumerate a data structure and have an iteratee do the output. Hmmm. Output-iteratees are a very, very, interesting thing to think about. [3] Anyway, they'd almost certainly annihilate all your worries about resource usage. [1] The original: http://okmij.org/ftp/Haskell/Iteratee/ Cabalised and improved (e.g. seek performance, identifier capitalisation): http://inmachina.net/~jwlato/haskell/iteratee/ Monadic Regions[2] might shed some light on Oleg's train of thought regarding all this [2] http://www.cs.rutgers.edu/~ccshan/capability/region-io.pdf [3] Which is just another way of saying "I'd rather shut up now, let me try it first" -- (c) this sig last receiving data processing entity.
