Ah, but Lua never had pack()/unpack() like you describe - they were
just put into the table namespace.

That is, pack makes a table from varargs.

Are you thinking of the pack defined in that varargs library?

I can't see how existing pack can be made more efficient - the varargs
need to be stored, and a table is a natural container for them.
