Greetings, ye Monks!

I'm using Moose for the first time, and I'm a little baffled by something.

I have an object attribute that is an arrayref. I'd like the writer for that attribute to append a value if I call the writer with a single valid value. How would I do that? Coercion doesn't look right, because I don't want to change the value, I want to change how the value is added. I've tried setting 'accessor' to a custom sub, but it didn't even get called. So, I'm asking you monks for help.

Here's an example-ish illustration of what I want.

Package Wibble;
use Moose;

has 'thingies' => ( is => 'rw', isa => 'ArrayRef' );

## Things I don't understand yet go here...

Package main;
use Wibble;

my $w = Wibble->new( thingies => [ 'this', 'that' ]);

print join(", ",$w->thingies())."\n";
# prints "this, that"

# here's the bit that I want to make work
$w->thingies('another');

print join(", ",$w->thingies())."\n";
# prints "this, that, another"

I hope that makes sense.

Thanks!
