Forbid the use of modules that are never used in your project.

A module is considered used if

• it contains a main function (be it exposed or not)
• it imports the Test module
• it is imported in any other modules, even if it is not used.
• the project is a package and the module is part of the elm.json's exposed-modules
• it is named ReviewConfig

config =
    [ NoUnused.Modules.rule
    ]

Try it out

You can try this rule out by running the following command:
