| Is it the same as this one? http://hackage.haskell.org/trac/ghc/ticket/1148
| I use qualified imports, and I see it on about half the modules I compile.
I don't think so. I believe the original message concerned a variable or type that was in scope in two different ways. Niklas said
| Generally, if module A exports foo, module B imports A and re-exports
| foo, and module C imports both A and B, there should be no ambiguity.
| Not even if it reexports all of modules A and B. Why would e.g. GHC
| need to warn in that case?
Perhaps Niklas can say whether #1148 is the bug he is describing, and if not file a new one?
