If you have a hash of hashes and you want to iterate across all values, what's the best way to do it. I would like to know if I coule iterate through Hash of hashes without using foreach twice (or number of times hashes are present). For example, I would like to do: 

foreach my ($key1, $key2)  (keys  %hoh)
{
### CODE ###
}

instead of 

foreach my $key1 (keys %hoh) 
    {
    foreach $key2 (keys %{$hoh{$key1}) 
    {
    ### CODE ###
    }
}

I hope there is some way to do it. Thanks
