groupBy

[Frederik Eaton]

Hello,

My copy of the library documentation says:

    groupBy :: (a -> a -> Bool) -> [a] -> [[a]]
    The groupBy function is the non-overloaded version of group.
    User-supplied comparison (replacing an Ord context)
    The function is assumed to define a total ordering.

But group has an Eq context. I don't understand how an Ord context
would even be used, or how the function argument of groupBy is meant
to define a total ordering. Is this a typo?

Frederik
