I'm developing a framework for artificial life experiments that I would like to make available on Hackage eventually. I've read all the guidance and proposals I could find for where to place packages in the hierarchy: http://www.haskell.org/haskellwiki/Hierarchical_module_names http://www.cs.york.ac.uk/fp/libraries/layout.html http://www.cs.york.ac.uk/fp/libraries/layoutSM.html I've also examined the current hierarchy of modules: http://hackage.haskell.org/packages/archive/pkg-list.html The current hierarchy has a top-level AI category, so it would seem logical to me to add a top-level ALife category and put my package under that. But perhaps it would be best not to start a new top-level category? I could put my package under AI, because my framework does support the use of AI, and wouldn't look too out of place with the other packages there. Thoughts?
