I have a test grammar that returns an array of hashes:

use Parse::RecDescent;
use Data::Dump::Streamer;

my $grammar = q{
    test: expr(s) /^\Z/
        {return $item{"expr(s)"};}

    expr: name '=' /\d+/
        {
        $return = {$item{name} => $item[-1]};
        1;
        }

    name: /\w+/
    };  

my $parser = new Parse::RecDescent ($grammar);

Dump ($parser->test ("x = 1\ny = 2\nz = 3"));

Prints:

$ARRAY1 = [
            { x => 1 },
            { y => 2 },
            { z => 3 }
          ];

but I'd like a simple hash:

$HASH1 = {
           x => 1,
           y => 2,
           z => 3
         };

For some reason my brain has frozen up and I just can't get the syntax right. What am I missing? (I'd rather Parse::RecDescent return the hash than fix it later.)
