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>
- --
You're in a maze of twisty little statements, all alike.
