| 40x40px | This module is rated as beta, and is ready for widespread use. It is still new and should be used with some caution to ensure the results are as expected. |
This module finds nil globals and adds the to the lua log along with where they were read/written. This module is different from Module:No globals as you can see all nil global variables that are being read/written to rather then only getting an error for the first problematic global variable. The arg variable is excluded.
