I'm working on a frontend for psc that prints original source ranges, so it makes it very easy to spot which errors have incorrect position reporting. This issue is to catalog all those we find so we don't have to make separate issues for them.

Edit (@paf31) Here is a list of all errors listed here. Let's check them off as they get fixed:

• NoInstanceFound
• WildcardInferredType
• TransitiveExportError
• UnknownType
• UnknownDataConstructor
• UnknownImportDataConstructor
• UnknownValue
• KindsDoNotUnify
• TypesDoNotUnify
• CycleInModules
• ShadowedName
• InfiniteType
• DuplicateModuleName
• CannotFindDerivingType
• MissingFFIImplementations
• CannotDerive
