ghc's only going to get confused if they're removed *during* compilation. Otherwise, the worst that happens is ghc has to recreate them during xmonad --recompile
But those .o files stay there, don't they? What happens if a second user --recompiles and ghc can't rewrite/delete those files due to ownership?
That's a good point; I hadn't thought of the name conflict. Between that and Brandon's security point (ghc might not reuse those files depending on how it checks for existing files, and one could probably solve it by forcing recompilation), I guess this isn't a good idea; I've marked it rejected on darcswatch. So, we could either wait until GHC implements and widely releases some -remove-intermediates option, or we could just go with Joachim's old strategy of manually removing the intermediates in .xmonad/: http://darcswatch.nomeata.de/bundles/8e8ad2f4b141e33c06490e60b15f3191f84a5cc... + hi = base ++ ".hi" + o = base ++ ".o" lib = dir "lib" libTs <- mapM getModTime .
