You could store the message definitions in an (external) xml configuration file.
use strict;
use XML::Simple;

my $msg = LoadMsgConfig();
print "$msg->{0}\n";      # look up by id
print "$msg->{thanks}\n"; # look up by mnemonics

sub LoadMsgConfig
{
    my $xs = new XML::Simple();
    my $xmlmsg = do { local $/; <DATA> };
    my $tags = $xs->XMLin($xmlmsg);

    return undef if ! defined $tags->{msg};

    my %msg;
    foreach (keys %{$tags->{msg}})
    {
        $msg{$_} = $tags->{msg}{$_}{text};
        $msg{$tags->{msg}{$_}{id}} = $msg{$_};
    }

    # undef $xmlmsg, $tags, $xs;
    return \%msg;
}

__DATA__
<?xml version="1.0"?>
<config>
  <msg id="0" name="wrong_input"  text="Wrong input"/>
  <msg id="1" name="thanks"       text="Thanks for signing up with us"
+/>
  <msg id="2" name="go_away"      text="Go away hacker"/>
</config>

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
