snowyy has asked for the wisdom of the Perl Monks concerning the following question:

I want the value of the first element in the first array, what is wrong with my code? 


$first = $stat_ref[0][0];

# $stat_ref is a hard reference to an array of arrays.

Tried this too but it didn't work. 
$first = $$stat_ref->[0][0];

    Your first example doesn't dereference $stat_ref. Your second example dereferences it twice. You have two options: 
    $first = $stat_ref->[0][0];
    # or
$first = $$stat_ref[0][0];

    I think this is documented in perlreftut. It's a hard concept to grok the first time around. I stumbled over it for a couple of weeks, myself.
