The most relevant (and recent) thread about this starts at
	http://lua-users.org/lists/lua-l/2006-11/msg00636.html

In particular, see these answers:
	http://lua-users.org/lists/lua-l/2006-11/msg00639.html
	http://lua-users.org/lists/lua-l/2006-11/msg00645.html

If you need C code for this, here it is:

#include "lua.h"

static int indexnil (lua_State *L) {
  return 0;
}

LUALIB_API int luaopen_nil (lua_State *L) {
  lua_pushnil(L);
  lua_createtable(L, 0, 1);
  lua_pushcfunction(L,indexnil);
  lua_setfield(L, -2, "__index");
  lua_setmetatable(L, -2);
  return 0;
}
