    I wouldn't use a case statement in this case though, this IMO looks better:

    tester :: Int -> String -> String
    tester x y | x < 0     = "less than zero. " ++ expr
               | otherwise = "greater than or equal to zero. " ++ expr
        where expr = if y == "foo" then "the name is foo." else "the name is not foo."
