Hello All (already...),

    This is a Lua bug? If you make:

    function x()
            local y,z
    end
    function z()
        local x = 10, y
    end

    Function x will have y and z local, but function z will have only x
local. I think this is a question to Luiz/Roberto.

                                                        The God's Peace,


Leandro.
