Objet : confused about reference



I was just testing some reference and while trying out below I am trying
to understand below

@{$yahoo->{yahoo}}........... I can see that this is pointing to 0,1,3
by running the code.
But I am trying to really understand whether this is trying to say since
value of 'yahoo' is array put @ at the front?

Here $yahoo is a hash reference (or say it's pointing to an anonymous hash), you could declare it as $yahoo = {};
$yahoo->{yahoo} points to a hash value whose key is 'yahoo'.
This value is an anonymous array, say it's $yahoo->{yahoo} = [1,2,3].
so @{$yahoo->{yahoo}} will derefer the anonymous array, you will get an array of (1,2,3) finally.
