Composition and inheritance: the Julian way

I found a way to avoid the copying involved in the super method defined in the first post. Simply use invoke.:yum:

The updated call(p::AbstractCitizen) is now:

function call(p::AbstractCitizen)
    if p.nationality == "Italian"
        print_with_color(:red, uppercase(p.name), " dove sei ?")
    elseif p.nationality == "UK"
        print_with_color(:red, uppercase(p.name), " where are you ?")
    else
        invoke(call, Tuple{AbstractPerson}, p) # invoke method using parent object
    end
end
