Add a flag to remove/delete intermediate files generated by GHC
See for example http://stackoverflow.com/questions/1411089/how-to-stop-ghc-from-generating-intermediate-files or http://www.haskell.org/pipermail/xmonad/2010-May/010180.html /
Currently GHC generates *.o and *.hi files for executables, possibly quite a few. They take up space, filenames, and interfere with tab-completion.
(And they may be worse than that. I occasionally see users in #xmonad who seem to have subtle compilation issues after upgrades linked to stale .hi and .o files.)
There doesn't seem to be any good way to remove the intermediates for a program like Xmonad. They can't be redirected to /dev/null, it's a potential security problem to redirect them to /tmp, and removing them manually is difficult (Xmonad could hardwire in removeFiles of 'xmonad.o' and 'xmonad.hi', but what about the arbitrary user modules in ~/.xmonad/lib? Now one needs to start working with globs or utilities like 'find'...).
Of course, GHC knows precisely what's being generated, and could easily remove them. So another flag in the line of -fforce-recompilation seems warranted; perhaps -fforce-no-intermediates?
