SPUG: In over my head with hashes of arrays of arrays

[Adam Monsen]

Good advice by all. Also, check out Data::Dumper, an invaluable tool
at examining data structures of any kind.

use Data::Dumper;
$myhash{evens} = [ [0,2,4], [4,6,8] ];
print Dumper(\%myhash); # notice the backslash!

prints out:

$VAR1 = {
         'evens' => [
                      [
                        0,
                        2,
                        4
                      ],
                      [
                        4,
                        6,
                        8
                      ]
                    ]
       };

There's also a cool replacement to Data::Dumper that prints out the
actual variable name instead of just $VAR1, but I forget what the name
of that module is. I suppose you can also use Data::Dumper->Dump(),
but this module that I can't remember the name of does everything for
you.
