As a point of curiosity, at least, I'm wondering why GHC does not allow mutally-dependent imports, as recursive dependencies doesn't seem to be a problem in any other area of Haskell. And I'm wondering if there is some kind of trick to get around this and allow the cyclic dependency.
Allowing mutually-dependent imports in all generality would complicate the task of GHC name resolution and type inference but if you're ready to do a bit more work, you can have cyclic dependency with an hs-boot file, see GHC doc : http://www.haskell.org/ghc/docs/latest/html/users_guide/separate-compilation... -- Jedaï
