newWildcardVar :: Name -> Kind -> TcM TcTyVar Source

Create a new meta var with the given kind. This meta var should be used to replace a wildcard in a type. Such a wildcard meta var can be distinguished from other meta vars with the isWildcardVar function.

newWildcardVarMetaKind :: Name -> TcM TcTyVar Source

Create a new meta var (which can unify with a type of any kind). This meta var should be used to replace a wildcard in a type. Such a wildcard meta var can be distinguished from other meta vars with the isWildcardVar function.
