-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I just tried some uses of the "default" keyword with Yhc that failed, and I didn't find any existing Yhc test-cases for this keyword. These all run with Hugs. Fails with Yhc: - ---------- import Ratio ( Ratio -- :: * -> * ) default (Ratio Integer) main = putStrLn "okay" - ---------- but works with Yhc: - ---------- import Ratio ( Ratio -- :: * -> * ) type RatioInteger = Ratio Integer default (RatioInteger) main = putStrLn "okay" - ---------- Fails (differently) with Yhc: - ---------- default(Rational) main = print (0.1 * 3 == 0.3) - ---------- but works with Yhc: - ---------- default(Rational) main = print ((0.1 :: Rational) * 3 == 0.3) - ---------- Isaac P.S. I know that type Rational = Ratio Integer -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFE5ZhcHgcxvIWYTTURAl9dAKCLUs9q1sxFVdWee2DJK2LDZf7HjgCgs/aK EI0FuUgMqK6OdAlJ+BP6zfE= =37e3 -----END PGP SIGNATURE-----
