I'd like to make a request that the HUnit testing framework be converted to a 'package' in the hierarchical libraries, to make for easier installation and use. If it could be added to the fptools repository, and so be distributed with new releases of ghc, Hugs, and nhc98, so much the better, but a separate distribution would be fine as well. The current distribution appears to be two years old, so I'm guessing it is pretty stable. I know it has several keen users, and making it more readily accessible would be a good goal. As far as locating it in the hierarchy is concerned, I would suggest the following renaming plan: HUnit -> Test.HUnit HUnitBase -> Test.HUnit.Base HUnitLang -> Test.HUnit.Lang HUnitLang98 -> Test.HUnit.Lang98 HUnitLangExc -> Test.HUnit.LangExtended HUnitText -> Test.HUnit.Text Terminal -> Test.HUnit.Terminal The other modules in the current distribution are unit tests for the testing framework itself, so do not exactly belong in the hierarchy: HUnitTestBase HUnitTest98 HUnitTestExc TerminalTest I imagine they could simply be retained as tests, but not installed. The top-level of the 'Test' hierarchy does not currently exist, but HUnit looks like an ideal candidate to start it off. [ For folks on the libraries list, I would also like to recommend that the existing 'QuickCheck' package move from its current location in 'Debug.QuickCheck' to 'Test.QuickCheck', which is more descriptive of its actual use. ] Regards, Malcolm
