mkTyClD :: LTyClDecl n -> LHsDecl n
mkClassDecl builds a RdrClassDecl, filling in the names for tycon and datacon by deriving them from the name of the class. We fill in the names for the tycon and datacon corresponding to the class, by deriving them from the name of the class itself. This saves recording the names in the interface file (which would be equally good).

cvTopDecls :: OrdList (LHsDecl RdrName) -> [LHsDecl RdrName]
Function definitions are restructured here. Each is assumed to be recursive initially, and non recursive definitions are discovered by the dependency analyser.

checkPartialTypeSignature :: LHsType RdrName -> P (LHsType RdrName)
Check the validity of a partial type signature. We check the following things:
- There should only be one extra-constraints wildcard in the type
signature, i.e. the
_
in_ => a -> String
. This would be invalid:(Eq a, _) => a -> (Num a, _) => a -> Bool
. Extra-constraints wildcards are only allowed in the top-level context. - Named extra-constraints wildcards aren't allowed,
e.g. invalid:
(Show a, _x) => a -> String
. - There is only one extra-constraints wildcard in the context and it must
come last, e.g. invalid:
(_, Show a) => a -> String
or(_, Show a, _) => a -> String
. - There should be no unnamed wildcards in the context.
- Named wildcards occurring in the context must also occur in the monotype.
An error is reported when an invalid wildcard is found.
checkNoPartialType :: SDoc -> LHsType RdrName -> P ()
Check that the given type does not contain wildcards, and is thus not a partial type. If it contains wildcards, report an error with the given message.
checkValidPatSynSig :: Sig RdrName -> P (Sig RdrName)
Check that the pattern synonym type signature does not contain wildcards.
checkDoAndIfThenElse :: LHsExpr RdrName -> Bool -> LHsExpr RdrName -> Bool -> LHsExpr RdrName -> P ()
checkRecordSyntax :: Outputable a => Located a -> P (Located a)
checkValidDefaults :: [LHsType RdrName] -> P (DefaultDecl RdrName)
Check that the default declarations do not contain wildcards in their types, which we do not want as the types in the default declarations must be fully specified.
