Re: [Haskell-cafe] What puts False before True?

Brandon,

If I'm reading the reports correctly, the Ord instance was actually added in the Haskell 1.1 standard, by changing the definition of Bool from

data Bool = True | False

to

data Bool = True | False deriving (Eq, Ord, Ix, Enum, Text, Binary)

It's data Bool = False | True

It seems like we actually get that order because deriving Ord makes constructors earlier in the definition compare greater than later constructors, and nobody was bothered by that ordering.

It's the other way around: data T = Less | More deriving (Eq, Ord) gives you *Main> Less < More True Cheers, Stefan
