Greetings, Monastery denizens: I've been struggling with this seemingly simple problem for a while, and would really appreciate some input from brains that are not mine. I have a data structure of arbitrary depth handed to me that is composed of hash/arrayrefs for which I need to create a path-type lookup. This is proving to be a pain, since I have to figure out what the structure is at every level - so I would really rather flatten it to hashrefs all the way down. The main fact here is that every hashref has a 'name' key in it pointing to a text value - so that's how I'd like to "re-key" this thing. Example: 
$foo = {
    [
        {
            name => 'a',
            type => 1,
            rockets => 2,
            leaves => 3
        },
        {
            name => 'b',
            type => 7,
            rockets => 4,
            leaves => 1,
            samples => [
                {
                    name => 'mary',
                    dog  => 'fifi'
                },
                {
                    name => 'john',
                    fish => 'oscar'
                }
            ]
        }
    ]
};

And here's what I'd like to produce (I don't care whether the { 'name' => 'value' } entry remains in the result or not): 
$foo1 = {
    a   => {
        name => 'a',
        type => 1,
        rockets => 2,
        leaves => 3
    },
    b   => {
        name => 'b',
        type => 7,
        rockets => 4,
        leaves => 1,
        samples => {
            mary => {
                name => 'mary',
                dog  => 'fifi'
            },
            john => {
                name => 'john',
                fish => 'oscar'
            }
        }
    }
};

Thanks in advance for the help!
