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.
