Why is it that this source file
-- begin code --
class Numeric a
where describe :: a -> String
instance Integral a => Numeric a
where describe n = "Integral"
instance Floating a => Numeric a
where describe n = "Floating"
-- end code --
produces the error message
-- begin code --
*** This instance : Numeric a
*** Overlaps with : Numeric a
*** Common instance : Numeric a
-- end code --
even though I have overlapping instances turned on. The "+o" option.
