I'm not sure what the right thing is here. I usually prefer to avoid re-exports because they create problems with warnings.
I think this is a bit sad actually. The situation discussed here is (IMO) exactly the kind of situation that re-exports are intended for. That some tools give warnings for re-exports is a flaw in those tools, not a problem with the re-export per se. 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? Cheers, /Niklas
