3. lookupHptDirectly :: HomePackageTable -> Unique -> Maybe HomeModInfo

4. lookupInstalledModuleEnv :: InstalledModuleEnv a -> InstalledModule -> Maybe a

5. lookupModuleEnv :: ModuleEnv a -> Module -> Maybe a

   ghc	GHC.Unit.Module.Env

   No documentation available.

6. lookupWithDefaultModuleEnv :: ModuleEnv a -> a -> Module -> a

   ghc	GHC.Unit.Module.Env

   No documentation available.

7. lookupModuleInAllUnits :: UnitState -> ModuleName -> [(Module, UnitInfo)]

   ghc	GHC.Unit.State

   Takes a ModuleName, and if the module is in any package returns list of modules which take that name.

8. lookupModulePackage :: UnitState -> ModuleName -> PkgQual -> Maybe [UnitInfo]

   ghc	GHC.Unit.State

   The package which the module **appears** to come from, this could be the one which reexports the module from it's original package. This function is currently only used for -Wunused-packages

9. lookupModuleWithSuggestions :: UnitState -> ModuleName -> PkgQual -> LookupResult

   ghc	GHC.Unit.State

   No documentation available.

10. lookupPackageName :: UnitState -> PackageName -> Maybe UnitId

    ghc	GHC.Unit.State

    Find the unit we know about with the given package name (e.g. foo), if any (NB: there might be a locally defined unit name which overrides this) This function is unsafe to use in general because it doesn't respect package visibility.
