EO::WeakArray - arrays where all references contained are weak
use EO::WeakArray;
my $thing = {};
my $array = EO::WeakArray->new;
$array->push( $obj );
$obj = undef;
if ( $array->at( 0 ) == undef ) {
print "ok\n";
}
A WeakArray is similar to a normal array only its contents are not reference counted. Thus, if something destroys the contents from the outside world then it disappears from inside the array as well.
WeakArrays provide no methods beyond those provided by an array.
