tcRnStmt :: HscEnv -> GhciLStmt RdrName -> IO (Messages, Maybe ([Id], LHsExpr Id, FixityEnv))

The returned [Id] is the list of new Ids bound by this statement. It can be used to extend the InteractiveContext via extendInteractiveContext.

The returned TypecheckedHsExpr is of type IO [ () ], a list of the bound values, coerced to ().

tcRnExpr :: HscEnv -> LHsExpr RdrName -> IO (Messages, Maybe Type)

tcRnType :: HscEnv -> Bool -> LHsType RdrName -> IO (Messages, Maybe (Type, Kind))

tcRnImportDecls :: HscEnv -> [LImportDecl RdrName] -> IO (Messages, Maybe GlobalRdrEnv)

tcRnLookupRdrName :: HscEnv -> Located RdrName -> IO (Messages, Maybe [Name])

Find all the Names that this RdrName could mean, in GHCi

getModuleInterface :: HscEnv -> Module -> IO (Messages, Maybe ModIface)

ASSUMES that the module is either in the `HomePackageTable` or is a package module with an interface on disk. If neither of these is true, then the result will be an error indicating the interface could not be found.
