Request fellow monks to have a look at the following code, 
use strict;
use warnings;
my @arr=(12,13,14);
my %hash=(
        "outer"=>(
            "cool"=>1,
            "Kewl"=>2,"odd"
        )
);
print keys %hash,"||",values %hash,"  ",$hash{"2"};

Though the right way to declare is like 
my %hash=(
        "outer"=>{
            "cool"=>1,
            "Kewl"=>2,
        }
);

I am intrigued after looking at the o/p.How come the supposed to be keys "cool","kewl" became values and values 1,2 became keys.What exactly is the effect of using '()' in-place of '{}'

The world is so big for any individual to conquer
