Re: [Haskell-cafe] Mutually recursive modules and google protocol-buffers

And there is no way ghc can compile these in separate modules.

I may be being redundant here, but you may not know that GHC actually can compile mutually recursive modules. See http://www.haskell.org/ghc/docs/latest/html/users_guide/separate-compilation... . Of course, this is not a great solution either, as creating hs-boot files is a bit tedious, but at least the option is there. Cheers, Max
