I suppose I could stuff a reference to the @ids array into 
$self->{term_ids}
like this:

  if (@ids) { $self->{term_ids} = [EMAIL PROTECTED] }
Exactly!

But then how do I dereference items in my object?
sub foo {
    my ($self) = @_;
    my $ids = $self->term_ids;
    # How to dereference a variable that holds an array ref:
    foreach (@$ids) { ... }
}
sub bar {
    my ($self) = @_;
    # How to dereference an expression that returns an array ref:
    my @ids = @{ $self->term_ids };
    foreach (@ids) { ... }
}
HTH,

Paul.
