Can you do two levels of includes?

Lets say I'm doing a many through, and I want the results from the join table as well. It could be a many on the first relationship and a one on the second, and result in something like this:

User = {name:'Fred', 'friendships': [{'user':{name:'Bob'}, confirmed:True}, {'user':{name:'George'}, confirmed:False}]}

Given tables like:

create table user (int id primary key, text name)
create table friendship (int sender_id references user, int receiver_id references user, bool confirmed)

I want this feature. Any idea what you think the configuration should look like? For instance, I'm working on a "many" relationship in my branch here: https://github.com/pifantastic/FastLegS/blob/master/test/integration/integration_test.js#L89

However, I'm stuck on what the configuration should be for a "has_many through" relationship.
