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.
