Thanks for your detailed answer. I finally understood this behaviour

Hi,
Below are two questions on commutative operations in Haskell.

com :: Int - Int - Int
x `com` y = (x + y)
commutative com a b = (a `com` b) == (b`com`a)
-- 1 + 3 == 3 + 1

after the plus operation

The darcs team is proud to announce the release of darcs 2.5. Darcs 2.5

Is really red a good color for links? At least for me, red links looks like

Another possible argument: large type classes can look daunting for
