Re: confused about reference

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

@{$yahoo->{yahoo}}........... I can see that this is pointing to 0,1,3 by running the code.
But I am trying to really understand whether this is trying to say since value of 'yahoo' is array put @ at the front?
or @ is there because it's array slice??
Can someone explain this?
@{$yahoo->{yahoo}} has @ on it because it's value of yahoo is reference. Is this right?

Also, %{$base[0]}, trying to understand this.
According to the tutorial,

%base referenced is %{$base}

what is the difference between %{$base[0]} vs %{$base}[0] Are we here talking about first being hash reference which first item is array reference vs second one is hash reference's first item ?
This one, I cannot figure it out............


thank you.

#!/usr/bin/perl

use warnings;
use strict;
use Data::Dumper;

my $yahoo = { 'yahoo' => [ 0, 1, 3],
'msn' => [ 12, 32, 44]
};

print Dumper($yahoo);

print "\n\n\n\n\n------------------------------------------------------------\n";


print "${$yahoo}{yahoo}[0]\n"; # prints 0
print "$yahoo->{yahoo}[0]\n"; # prints 0
print "@{$yahoo->{yahoo}}\n"; # prints 0,1,3
print "%{$yahoo->{yahoo}}\n"; # print %{ARRAY(0x832e8c4)}
