Ok, but actually I would use this and maybe put the MyParser package to a different file (but not everybody like OO): 
package MyParser;

use constant DEBUG => 1;

use strict;
use base qw(Parse::RecDescent);
use Data::Dumper;

sub new {
    print "MyParser->new(@_)\n" if (DEBUG);
    my ($class, $szGrammar, $szCode) = @_;

    my $this;
    eval {
        $this = $class->SUPER::new($szGrammar);
    };
    if ($@) {
        print $@;
        $this = {};
        bless $this, $class;
    }
    else {
        # Start parsing code
        $this->test($szCode);
        return $this;
    }
}

sub AddToHash {
    print "MyParser->AddToHash(@_)\n" if (DEBUG);
    my ($this, $szVar, $szValue) = @_;

    $this->{Result}->{$szVar} = $szValue;
}

sub GetResult {
    print "MyParser->GetResult(@_)\n" if (DEBUG);
    my ($this) = @_;

    return $this->{Result};
}

sub DumpResult {
    print "MyParser->DumpResult(@_)\n" if (DEBUG);
    my ($this) = @_;

    print Dumper($this->{Result});
}


package main;


my $szGrammar = q{
    test: expr(s) /^\Z/

    expr: name '=' /\d+/
        {
            $thisparser->AddToHash($item{name}, $item[-1]);
        }

    name: /\w+/
    };

my $szCode = "x = 1\ny = 2\nz = 3";

my $hParser = MyParser->new($szGrammar, $szCode);
$hParser->DumpResult();
