Good question. I often need to export a name to other modules within the hierarchy, but without making them visible outside it. I've "solved" this problem by giving them funky names and adding a comment, but is there a more structured way to do this? A quick google hasn't found one yet.

Assuming you're writing a cabal package, you could separate the interface from the actual implementation: ------------------------------------------------------------------------ module Hello ( hello ) where import Hello.Impl ------------------------------------------------------------------------ module Hello.Impl ( hello, hello_internal ) where hello, hello_internal :: String hello = "Hello, world!" hello_internal = "The secret word is 'puddleplum'." ------------------------------------------------------------------------ and then list Hello.Impl under extra-modules instead of exposed-modules in the cabal file, which will hide it from external users. Internal users can just use Hello.Impl directly. HTH, Bertram
