If you start a function name with an underscore, it is "implicitly
exported" by GHC (I can't find the actual documentation page at the
moment however).  Whilst it may not appear in the export list, you are
still able to call it from outside the module.

This will, however, result in "ugly" function names as well as
possibly still have those items appear in the haddock documentation...
