More or less. The macros lua_ref/lua_unref/lua_getref are for
compatibility, but the functions luaL_ref/luaL_unref are not. That is,
Lua keeps a reference mechanism, but now you can choose to put your
stuff into the registry or into a private table of yours (which may be a
weak table, for instance).
