I've written this: 
$hash{tree} = 4;
$hash{tree}->{apple} = 6;
$hash{tree}->{apple}->{red} = 9;
$hash{tree}->{apple}->{fuji} = 4;

$hash{bird} = 4;
$hash{bird}->{robin} = 4;

$hash{snail} = 4;


foreach $key (keys %hash)  {
    print "$key   ".$hash->{$key}."\n";

    foreach $key2 (keys %{$hash->{$key}})  {
        print "$key   $key2   ".$hash->{$key}->{$key2}."\n";

        foreach $key2 (keys %{$hash->{$key}->{$key2}})  {
            print "$key   $key2   $key3   ".$hash->{$key}->{$key2}->{$
+key3}."\n";
        }
    }
}

But when I run it, I only get the first-level keys (but not the associated first-level value).

This, in theory, should reprint my inputs without the '$hash' and the braces (but not necessarily in the order entered).

Is this not an appropriate way to use a hash? And how do I fix what's wrong?

Thanks!
