Some people might be quite excited by Milan's work on significant
performance improvements to the containers package...

I did quite a lot of benchmarking, strictness analysis and performance
improvements to the containers package recently, see the draft of my
paper http://fox.ucw.cz/papers/containers/containers.pdf.

Next week I will start finalizing the patches and submit them. The 'not
generating a worker/wrapper' issue is one of several on my radar, so
this should be resolved.
