Not sure i like the lock-in you get with the anon sub approach. I would make the config hash have both the sub references and the options references -- that way if you ever needed to override the options, it's a bit cleaner

   ....
  my $calls => {
     A => { sub_ref => \&print_A, config_ref => { ... } },
     B => { sub_ref => \&print_B, config_ref => { ... } }
  };

  my $test = 'A';
  my $sub  = $calls->{$test}{sub_ref};
  my $config = $calls->{$test}{config_ref};

  $sub->( $config );
