Comment (by thomie):

 > Also, have I missed something?

 Maybe. Check out:
  * -dynamic
  * -dynamic-too
  * -dyno
  * -dynosuf

 * Should intermediate files also get deleted when using `--cleanup` to
 create shared libraries
 (https://downloads.haskell.org/~ghc/7.10.3/docs/html/users_guide/using-
 shared-libs.html)?

 * What happens on compilation failures. Say `A.hs` contains a syntax
 error, and imports `B.hs`. When running `ghc --cleanup A.hs`, `B.hs` gets
 compiled first, creating `B.hi` and `B.o`. Then `A.hs` fails to compile,
 because of the syntax error. Should `B.hi` and `B.o` get deleted?

 * Is `ghc --make --cleanup` allowed? Maybe the command line interface
 should be something like `ghc --make -cleanup` (so `-cleanup` would not be
 a mode flag, but a regular flag, just like for example `-keep-tmp-files`
 and `-outputdir`.).
