Perhaps this is simple wording issue...

Assuming a class 'List' extending 'Object':

-- define the class
local super = Object
local self = super()
	
-- method for initialization
function self:init( aContent, aMode )
    self = super.init( self )
 	
    -- do subclass stuff
	
    return self
end

'self' and 'super' are sufficiently OO for any practical purpose.
Additionally, 'super' is properly scoped as well.
