Code review comment for lp:~axwalk/juju-core/agent-setapihostports

+ conf.SetAPIHostPorts([][]instance.HostPort{
+ instance.AddressesWithPort(server1, 123),
+ instance.AddressesWithPort(server2, 124),
+ instance.AddressesWithPort(server3, 125),
+ })
+ addrs, err = conf.APIAddresses()
+ c.Assert(err, gc.IsNil)
+ c.Assert(addrs, gc.DeepEquals, []string{"0.1.2.3:123", "0.1.2.5:125"})

Does conf.APIAddresses return a set or an ordered list ?
