in reply to length or array in a hash

Hi, ongaku,
You can do like so: 

%hash = (
        'one' => [1],
        'two' => [2,2],
        'three' => [3,3,3],
);

  foreach my $array (keys %hash){
      print $array," :", scalar @{$hash{$array}},$/;
  }

Output 
three :3
one :1
two :2

You might want to check the function scalar

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
