Dear Monks

I tried to put a hash from a sub directly into a foreach loop, like this
#! /usr/bin/perl

use strict  ;
use warnings ;


foreach ( keys &testa ) {
    print "key is $_\n" ;
}

sub testa {
    my %s ;
    $s{'a'} = 10 ;
    $s{'b'} = 20 ;
    $s{'c'} = 30 ;

    return %s ;
}

this looks like good perl programming to me, but it doesn't work however :(
(It makes me feel like a beginner)
Any suggestions ?

Thnx LuCa

UPDATE: I've update the sub and replace % into $
