Monad.Reader article (Multiset partitions)

I imagine that most who read this blog have already seen it, but for those who haven’t, my article Generating Multiset Partitions has been published in Issue #8 of The Monad.Reader.  In it, I discuss the problem of generating multiset partitions in a functional context, and give an implementation in Haskell.  The final published version contains many major improvements over the draft version I posted here a while ago; give it a read and let me know what you think if you’re interested!
