Re: Making Lua lexically scoped (was: Re: Proper tail recursion)

["John Belmonte" <jvb@...>]

I understand Lua programs much better than scoping lingo.  Lua upvalues
cannot be said to be lexically scoped because the following program prints
"5" instead of "10"?

    do
        local a = 5
        local foo = function() print(%a) end
        a = 10
        foo()
    end
