Dear Masters,
Just simple question. Given this array 
my @array = qw (foo bar qux);

How can I generate/initialize a Hash of Hash of Array like this with Map: 

my $VAR1 = { 
             'foo' => { 'foo' => [],
                        'bar' => [],
                        'qux' => [] },
             'bar' => { 'foo' => [],
                        'bar' => [],
                        'qux' => [] },
             'qux' => { 'foo' => [],
                        'bar' => [],
                        'qux' => [] },
};

I can do it with double foreach but since in the actual situation the array is very large (ten thousand elements ore more) and I need it to be super fast. I suppose 'map' is the answer?
