Yes, we can now use Agents in Gobo. The restrictions depend
on whether we will continue to support SE 1.2 or not.
Colin's and my messages on SE 1.2 mailing list have received
no answer for the past month.
If we still support SE 1.2, then the restrictions are that
you need to pass manifest tuples when calling an Agent.
And we should consider Agents as being novariant on the
Tuple part (ECMA considers them covariantly and SE contravariantly).
