the two following bits of code produce to different outputs when the main variable '%args' is viewed with the 'x' command in the debugger.

i'm hoping that someone can explain what i'm seeing.

run a script with the following code 

    
    my %args;
    $args{'expr'} = \['booya' 'kada'];

then perform 'x \%args'...you'll see this: 
  DB<2> x \%args
0  HASH(0x1cb3778)
   'expr' => REF(0x1a35d54)
      -> ARRAY(0x1ca0124)          (WHY AN ARROW?)
            0  'booya'
            1  'kada'

[download]
then run the followin in a script: 
    my %args;
    my @ary;
    @ary = ['booya', 'kada'];
    $args{'expr'} = \@ary;

[download]
in this case 'x \%args' produces: 
  DB<3> x \%args
0  HASH(0x1cb3778)
   'expr' => ARRAY(0x1cb3844)
      0  ARRAY(0x1cea068)          (WHY A ZERO?)
         0  'booya'
         1  'kada'

so my question is this: what to the ARROW & ZERO signify and what is the difference. i'm guessing its related to anonymity, but i don't know and i believe there is a gem of knowledge here i don't want to lose.

i suppose a second question is this: where could i have found this answer myself - any documentation that explains debugger command outputs (in detail).

thanks in advance, nebbish
