Hi, what options do you have :set when seeing this behaviour? (i.e., I'm having trouble reproducing it here.) --sigbjorn ----- Original Message ----- From: "Shawn P. Garbett" To: Cc: "Dean Herington" Sent: Thursday, January 31, 2002 06:39 Subject: Bug in show instance

The following code generates some unexpected behavior (at least to me) in hugs (Feburary 2001: hugs 98 compatibility)

- ----------------------------------- main = print(show test)

newtype Out a = MkOut (String, a)

instance (Show a) => Show (Out a) where show (MkOut (x,y)) = x ++ " value: " ++ show y

test = MkOut("Blah\nBlah", 4) - --------------------------------------

Hugs Output:

Main> test ("Blah\nBlah",4) (20 reductions, 55 cells) Main>

- ------------------------------

GHCi (and expected output):

Main> test Blah Blah value: 4 Main>
