Then you have a problem. That's also the reason why I promote qualified 
and explicit imports again and again. If code can no longer be compiled, 
the compiler cannot help anymore.

Btw. there is another nice flag -fwarn-missing-import-lists that warns 
about unqualified implicit imports. It should be enabled in the 
Cabal.GHC-Options field.
