I have a class, with a member variable "A" that's an array reference. the array holds references to hash tables. currently, the array is a package level variable, although i'm not against changing this to a "self" variable. anyways, what is the best way to free all the hash references in the array, and the array from memory in "cleanUp?" 
package MyObject;

my @a = ();

sub new {
    my $class = shift;
    my $self = {};
    bless $self, $class;
    return $self;
}

sub A {
    my $self = shift;
    return \@a;
}

sub fillIt {
    my $self = shift;
    my %hash = ();
    
    my $i = 0;
    for($i=0; $i<10; $i++) {
        $hash{"key_$i"} = $i;
    }
    
    push(@a, \%hash);
}

sub cleanUp {
    my $self = shift;
    
    #??????????????????????????????????????????????????
    # best way to deref entire @a?
    #??????????????????????????????????????????????????
}

return 1;
