Hash within array, within hash, within array...
I have a little problem. To keep a configuration simple, I've exceeded my perl knowledge. :-) I've worked with multi-dimentional arrays before, but this one has me beat:

Code:
@info = (
    {
        'defval' => 'abc'
        'stats' = (
            { 'name' => 'a', },
            { 'name' => 'b', },
        ),
    },
    {
        'defval' => 'def'
        'stats' = (
            { 'name' => 'd', },
            { 'name' => 'e', },
        ),
    },
);

my @infolist = $info[0]->{stats};    # I have a feeling this is where I'm going wrong...

print $infolist[0]->{name};    # <-- works!
print $infolist[1]->{name};    # <-- does not!

Like I said, I've exceeded my perl knowledge. :-) Can anyone see where I'm going wrong? The idea, of course, is to be able to get those 'name' key values... :-)

Thanks,
js.

Audio::MPD::Common::Stats(3pm)				User Contributed Perl Documentation			    Audio::MPD::Common::Stats(3pm)

NAME

       Audio::MPD::Common::Stats - class representing MPD stats

VERSION

       version 1.120881

DESCRIPTION

       The MPD server maintains some general information. Those information can be queried with the mpd modules. Some of those information are
       served to you as an Audio::MPD::Common::Stats object.

       An Audio::MPD::Common::Stats object does not update itself regularly, and thus should be used immediately.

       Note: one should never ever instantiate an Audio::MPD::Common::Stats object directly - use the mpd modules instead.

ATTRIBUTES

   $stats->artists;
       Number of artists in the music database.

   $stats->albums;
       Number of albums in the music database.

   $stats->songs;
       Number of songs in the music database.

   $stats->uptime;
       Daemon uptime (time since last startup) in seconds.

   $stats->playtime;
       Time length of music played.

   $stats->db_playtime;
       Sum of all song times in the music database.

   $stats->db_update;
       Last database update in UNIX time.
