Could you do the parameter building as constructor rather than setting the
fields manually?  In which case you might be able to make the fields final in
the params objects which might be an advantage.

[qsr, 2014/08/22 08:11:18]

 The generation of the message is the standard struct generation, so I cannot
easily change anything. Moreober, I need to deserialize the message in the stub,
so I cannot have the field as final given the way deserialization works.
