Actually, you're almost there... You use _['sequence-item'] to look up a
variable called sequence-item in the namespace.... similarly, you can do
_[_['sequence-item']] to look up sequence-item, and then look up that string
in the namespace. So, _[_['sequence-item']].absolute_url() will give you the
URL of that object.
