This is very handy, as well as the related 'lua -w' flag.

That said, if you have the misfortune to require a module, you are 
toasted:

lua -w Test.lua
lua: attempt to access undefined variable '_NAME'
stack traceback:
        [C]: ?
        [C]: in function 'module'
        .../socket.lua:14: in main chunk
        [C]: in function 'require'
        Test.lua:10: in main chunk
        [C]: ?
