There's also the full, proper perl API.

Whereas, I see simple RFC822 style forms as somewhat of a win over more
complex datastructures for remote resource munging. It's all a matter

It should certainly work to add someone to a list (such as should
already work for Requestor/Cc/AdminCc on tickets)
