Documentation
A typecheckable thing available in a local context. Could be
AGlobal TyThing, but also lexically scoped variables, etc.
See TcEnv for how to retrieve a TyThing given a Name.

tcExtendLetEnv :: TopLevelFlag -> TcSigFun -> IsGroupClosed -> [TcId] -> TcM a -> TcM a Source #
tcExtendSigIds :: TopLevelFlag -> [TcId] -> TcM a -> TcM a Source #

tcLookupTcTyCon :: HasDebugCallStack => Name -> TcM TcTyCon Source #

tcAddPatSynPlaceholders :: [PatSynBind GhcRn GhcRn] -> TcM a -> TcM a Source #
tcInitOpenTidyEnv :: [TyCoVar] -> TcM TidyEnv Source #
Get a TidyEnv that includes mappings for all vars free in the given
type. Useful when tidying open types.
isBrackStage :: ThStage -> Bool Source #
newDFunName :: Class -> [Type] -> SrcSpan -> TcM Name Source #
Make a name for the dict fun for an instance decl. It's an *external* name, like other top-level names, and hence must be made with newGlobalBinder.
