Dear Monks, I have this piece of code: 
my %vals=( 1 => '0', 2 => '3', 3 => '5');
my @arr = ( 0,1,2,3,4,5,6 );

my @res;
for my $key ( sort{ $a <=> $b } keys %vals ){
  push @res, $arr[$vals{ $key }];
}

print join (',', @res );

I am not good at writing compact code but I did not see any way to simplify this to a one liner or so. I am looking forward to your suggestions.
I tried to somehow get an array slice that would go into a line like 
print join (',', @arr[@res] );

but then thought there must be an even more compact way.

UPDATE: I changed one line in the above code to show what I wanted to use @arr for. Thanks ysth. The old line was 
  push @res, $vals{ $key };
