Fwd: How to forward declare globals

[Charles Smith <cts.private.yahoo@...>]

It's said that it's not necessary to have forward declarations, but then what's wrong with this:

    v = m1

    function m1 ()
        print ("hello world")

    function m1 ()
        print ("hello world")
    end

    v = m1

    v()
