I have a Tk callback where I give it as arguments an anonymous hash, like so: 

$canvas->bind($dk_img, "<Button-1>", [\&frst_clk,
      { deck => $deck, waste => $waste, img => $dk_img }]);

Well, after some experimentation, I realized the placement of how I get at the arguments is VERY important (i.e., if I don't shift the first arg off--an implicit Tk object, in this case a canvas--getting at the other one is a mess).

However, even after this, I cannot seem to get at the other argument. I'm getting unitialized errors, so I 'Data::Dumped' it, resulting in this: 

$VAR1 = {
          'deck' => bless( {
                             'next' => 0,
                             'num' => 0,
                             'max' => 52,
                             'cards' => [
                                          bless( {
                                                   'state' => 'up',
                                                   'where' => $VAR1->{
+'deck'},
                                                   'value' => 'j',
                                                   'suit' => 's'
                                                 }, 'Card' ),
...more blessed cards...
                                          bless( {
                                                   'state' => 'down',
                                                   'where' => $VAR1->{
+'deck'},
                                                   'value' => 5,
                                                   'suit' => 'c'
                                                 }, 'Card' )
                                        ]
                           }, 'Pile' ),
          'img' => 12,
          'waste' => bless( {
                              'next' => 0,
                              'num' => 0,
                              'max' => 52
                            }, 'Pile' )
        };

Well, I know I have what I want, so its a tricky matter of dereferencing, or what not. I figured it was an anonymous array, so I tried: 

$_->{deck}

## to no avail, so then I tried:

$_{deck}

## then:

${@_{deck}}

## and a bunch of other big and baggy monsters ...

How do I get at the data?

(incidentally, this is the result of a rewrite of some code I posted before about a solitaire program, viewable on my sketch pad...soon)
