Hi Mojo users,

I am trying to understand why the last statement in this code is return 0 
instead of 1.

use Mango;
>
> my $mango = Mango->new('mongodb://localhost:27017');
>
> my $db = $mango->db('test');
>
> my $coll = $db->collection('c');
>
> $coll->insert({"f" => "a" });
>
> my $list = $coll->find()->all();
>
> print scalar @{$list};
> #1
>
> print $coll->find()->count();
> #0
>
>
What am I not understanding? 

Thank you in advance
