You just have to dereference the array in your method body and you can do normal array operations like shift, pop, etc. 

sub addThings {
    my ($self, @new_things) = @_;
    push @{$self->{things}}, @new_things;
}
sub getThings {
    my ($self) = @_;
    # If the caller expects a list, then dereference the array 
    # before returning it, otherwise just return the reference.
    return wantarray ? @{$self->{things}} : $self->{things};
}

Of course you can use embedded hashes too if you can guarantee uniqueness of keys.
