-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
Illegal instance declaration for `MyClass (HashTable String String)' (The instance type must be of form (T a b c) where T is not a synonym, and a,b,c are distinct type variables) In the instance declaration for `MyClass (HashTable String String)'
even though the documentation in GHC states that HashTable is declared as "data".
(Guessing) Maybe because 'String' is not a type variable?
*Exactly* because of that. Cheers, Stefan -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (Darwin) iD8DBQFD93DyX0lh0JDNIpwRAuuWAJ9tT1n0RqDTP7yfJKGLLVDv6Nxf6wCfX6um NsEcRI/1PSif8RVkK28SOjI= =AhuP -----END PGP SIGNATURE-----
