如果您引用的是vararg函数，则arg表 table.pack 来如果需要，请创建arg:

If you are referring to vararg function, the arg table was deprecated already in Lua 5.1. In Lua 5.2, you can use table.pack to create arg if you need it:

function debug(name, ...)
    local arg = table.pack(...)
    print(name)
    for i=1,arg.n do
        print(i, arg[i])
    end
end
