$self->fail;

$self->fail($method_name, %args);
$self->fail($method_name);

The fail method exits the program with a 1 exit code. Optionally, you can call a handler before exiting by providing a method name with arguments. The handler will be called using the handle method so the arguments should be key/value pairs.
