If required/used, the following gives Unknown error: 

use strict;
BEGIN { test; }

When in -e or the file specified to perl, the following gives the apppropriate error message: 

use strict;
BEGIN { test; }

The following gives the apppropriate error message: 

use strict;
test;

The following gives the apppropriate error message: 

use strict;
BEGIN { test(); }

BEGIN { $var; }
