this seems to work:
I would hack the actual unpack function Lua uses (maybe creating a new
version). I'm just writing this right here so I don't know if
this code works:
static int luaB_unpack (lua_State *L) {
int n, i;
luaL_checktype(L, 1, LUA_TTABLE);
i = luaL_optint(L, 2, 1);
n = luaL_optint(L, 3, luaL_getn(L, 1));
luaL_checkstack(L, n, "table too big to unpack");
for (i=1; i<=n; i++) /* push arg[1...n] */
lua_rawgeti(L, 1, i);
return n;
}
