If you are going to use lua_createtable, it would be slightly better to
include space for the extra string:

-   lua_createtable(L,0,(sizeof(myLib)/sizeof(const struct luaL_Reg))-1);
+   lua_createtable(L,0,(sizeof(myLib)/sizeof(const struct luaL_Reg)));

(As an unrelated note, it seems simpler to write 'sizeof(myLib[0])'
instead of 'sizeof(const struct luaL_Reg)'.)
