You don't "need" to, but the luaL_register call does two very
different things whether you pass a string or not. Both are
acceptable, depending on your intent. But I don't know your intent
there. A simple luaopen_ function creates a Lua table, put some stuff
in that table, and somehow pass it back to require. That table is then
called a "module". Your luaopen_ function does something completely
different. It is perfectly valid, provided you understand what you are
doing.

To sum it up, what do you intend to do with that call to luaL_register?
