hpack is a bit dumb when generating the list of modules for a cabal file's component if multiple of them live in the same directory. Specifically it seems to assume that all modules in the source-dirs of a particular component are also necessary for its compilation. This is quite bad in the case of xanthous since both library and executable have source-dirs: src, so all modules will be compiled twice: Once for the library and then again for the executable despite it depending on the library (actually 4 times in total since we need to build a unprofiled and profiled object for each module…). To fix this we just move Main.hs into its own directory and change the executable's source-dirs, so hpack doesn't get confused anymore. Since all components now have their own source-dirs, unnecessary redundant compilation should be down to 0. The diff of the cabal file shows quite nicely how many module recompilation we've gotten rid of.
