MooseX::GetOpt just translates options to following call to Getopt::Long::Descriptive

use Getopt::Long::Descriptive;

my ($opt, $usage) = describe_options(
    'usage: mxgotest.pl [-?] [long options...]',
    [   'help|usage|?!' => 'Prints this usage information.' ],
    [   'name=s'        => 'Sets the name', { required => 1 } ],
);

The message is caused by required parameter. From the GLD docs:

If an option is required, failure to provide the option will result in describe_options printing the usage message and exiting.

I would remove the required from the name attribute and implemented the functionality after new_with_options call.
