Interesting. I needed to generate some integer partitions myself for something I was working on the other day and I was surprised to discover that there wasn't anything already available on CPAN.

I searched around, and ran across the same paper. I imemplented both algorithms proposed by Zoghbi and Stojmenovic in that paper, to permit forward and reverse lexicographic orderings and released it as a module.

My only comment is that while your code is very consice, I think you have removed the constant average delay property that the original algorithm features. The algorithm only requires two scalars to maintain state, so it's not as if its a memory pig.
