The idea of the fix is to teach GHC to warn about home modules (not from an other package), that are not explicitly listed in command line. Option name `-Wmissing-home-modules` is a subject for bikeshedding. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13129 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

The problem: when user fail to list a module in cabal file, then the package successfully builds, but the corresponding `.o` file is not included into the library. As a result, the package is unusable. One can argue that it is Cabal issue, and GHC has nothing to do with that. But fixing it on Cabal side is relatively hard. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13129#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
