Look again. Duplicate letters work.

However, ActivePerl v5.6.1 build 633 actually returns unshuffled results for "rotohotel", "r1t2h3tel" and "r1t2h3tels"!! Nothing guarantees that order is lost in a hash.

May I recommend a variation:

$_='rotohotel';
my $len;
my %f=map {rand() . '|' . $len++ => $_} split //;
print join('', values %f), "\n";

It seems values() is implemented as map { $hash{$_} } sort keys %hash) on this build!!

Update: ok, so it's not always sorted:

%hash = map { $_ => $_ } qw(m i f e z l x v b r d o h y j q s t k n g 
+c a p w u);
print(join('', values(%hash)), "\n");
# prints: abcdefghijklmnopqrstuvwxyz    SORTED

%hash = map { $_ => $_ } qw(m i f e z l x 2 v b r d o h y j q s t k n 
+g c a p w u);
print(join('', values(%hash)), "\n");
# prints: abcdefghijklmnop2qrstuvwxyz    NOT SORTED

%hash = map { $_ => $_ } qw(6 3 5 0 1 2 9 8 7 4);
print(join('', values(%hash)), "\n");
# prints: 0123456789    SORTED

%hash = map { $_ => $_ } qw(6 3 5 0 34 1 2 33 9 8 7 4);
print(join(':', values(%hash)), "\n");
# prints: 0:1:2:3:4:5:6:7:8:9:33:34    SORTED

%hash = map { $_ => $_ } qw(a aaaaaaa aaaa aaa aa aaaaa aaaaaaaaaa);
print(join(':', values(%hash)), "\n");
# prints: aa:aaaaaaa:a:aaaaaaaaaa:aaaaa:aaaa:aaa    NOT SORTED
