hi Ugo,
In ROS, a topic can only carry messages of a single type. We decided
early on that it would be too confusing if a topic could be of
multiple types. So roscpp doesn't support multi-type callback
registration.
(Note that the type of a topic actually can change over time, as it's
determined by the publisher that most recently advertised the topic.
But in a well-behaved ROS system, topics are stably typed).
