I'm not sure there's any information on building such a thing - but actually doing so wouldn't be too hard.
This is just a quickie I knocked up to test the idea. You could probably make it all objecty, and moosey if you preferred:
package Object::Holder;
use strict;
use warnings;
=head1 NAME
Object::Holder - A module for working with parameters.
=head1 SYNOPSIS
=for example begin
#!/usr/bin/perl -w
use Object::Holder
use strict;
my $helper = Object::Holder->new( foo => "bar",
bar => "baz" );
my @keys = $helper->param();
my $bar = $helper->param( "bar" );
=for example end
=cut
sub new
{
my ( $proto, %supplied ) = (@_);
my $class = ref($proto) || $proto;
my $self = {};
$self->{ "data" } = {};
#
# Store the supplied key=>val pairs in our data section.
#
foreach my $key ( keys %supplied )
{
$self->{ "data" }->{ lc $key } = $supplied{ $key };
}
bless( $self, $class );
return $self;
}
sub param
{
my ( $self, $param ) = (@_);
if ($param)
{
# return the value of the named param.
return ( $self->{ "data" }->{ $param } );
}
else
{
# return all the param names.
return ( keys %{ $self->{ "data" } } );
}
}
1;
package main;
my $o = Object::Holder->new( foo => "foo", steve => "kemp " );
#
# Get all
#
my @params = $o->param();
foreach my $param (@params)
{
#
# Get single
#
print "READ: $param -> " . $o->param($param) . "\n";
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
