I have discovered something that maybee someone could find intressting: 
#!usr/bin/perl -w
use strict;

my (%hash)=('A'=>1, 'B'=>2, 'C'=> 3);

rutine(\%hash);

sub rutine
{    
    my ($hash)=@_;
    print "$hash{A} $hash{B} $hash{C}\n";    
}

[download]
acctually prints: "1 2 3" while.. 
#!usr/bin/perl -w
use strict;

(my ($hash))=rutine();

print "$hash{A} $hash{B} $hash{C}\n";    

sub rutine
{    
    my (%hash)=('A'=>1, 'B'=>2, 'C'=> 3);
    return(\%hash);    
}

[download]
..doesn´t. What is the cause of this?
