    -- The 'Wrapped' class provides similar functionality as @Control.Newtype@,
    -- from the @newtype@ package, but in a more convenient and efficient form.
    --
    -- There are a few functions from @newtype@ that are not provided here, because
    -- they can be done with the 'Iso' directly:
    --
    -- @
    -- Control.Newtype.over 'Sum' f ≡ '_Unwrapping' 'Sum' 'Control.Lens.Setter.%~' f
    -- Control.Newtype.under 'Sum' f ≡ '_Wrapping' 'Sum' 'Control.Lens.Setter.%~' f
    -- Control.Newtype.overF 'Sum' f ≡ 'mapping' ('_Unwrapping' 'Sum') 'Control.Lens.Setter.%~' f
    -- Control.Newtype.underF 'Sum' f ≡ 'mapping' ('_Wrapping' 'Sum') 'Control.Lens.Setter.%~' f
    -- @
    --
    -- 'under' can also be used with '_Unwrapping' to provide the equivalent of
    -- @Control.Newtype.under@.  Also, most use cases don't need full polymorphism,
    -- so only the single constructor '_Wrapping' functions would be needed.
    --
    -- These equivalences aren't 100% honest, because @newtype@'s operators
    -- need to rely on two @Newtype@ constraints.  This means that the wrapper used
    -- for the output is not necessarily the same as the input.
