    # - File Variables
    #   you can still use and exclamation mark ! in front of a variable to say not to use it.
    #   Example !$test will match any file that is not a go test file.
    #
    #   `$all` - matches all go files
    #   `$test` - matches all go test files
    #
    # - Package Variables
    #
    #  `$gostd` - matches all of go's standard library (Pulled from `GOROOT`)

    # Default: Only allow $gostd in all files.
