Note that .n appears _only_ in the return value of table.pack, and
no other Lua function uses it. It is there so that the construction

   local arg = table.pack(...)

is all you need to get a Lua 4.0 program that depends on arg
all around the code to work in later versions of Lua.

If it really annoys people so much, they can put in a simple

   whatever_you_prefer, arg.n = arg.n
