Dear Monks,

I have a snippet of code:

use strict;
use warnings;
use DBI;
use Data::Dumper;
use IO::Prompt;
use PDF::Reuse;

my $choice = prompt 'Please choose your report output format...', -1,
  -menu => [ 'Console', 'PDF', 'HTML', 'Quit', ];

print "You chose: [$choice]\n\n";

my $action_ref = {
    'Console' => \&print_console,
    'PDF'     => \&generate_pdf,
    'HTML'    => \&generate_html,
    'Quit'    => sub { print "Exiting...\n"; exit 0; }
};

if ( $action_ref->{$choice} ) { $action_ref->{$choice}->(); }
else { warn "Unknown option: '$choice';\n" }

Why does print Dumper($action_ref); give:

$VAR1 = {
          'HTML' => sub { "DUMMY" },
          'Quit' => sub { "DUMMY" },
          'Console' => sub { "DUMMY" },
          'PDF' => sub { "DUMMY" }
        };

and not what's actually in the subs, which are further down the program?

A simple pointer to the docs I missed will do ;-)

Thanks,
Gavin.
