Description
The very first usage most people see in https://docs.ros.org/en/rolling/Tutorials/Beginner-Client-Libraries/Using-Parameters-In-A-Class-CPP.html
is really complicated and verbose.
Most nodes, most of the time, get their read-only params up front a single time, and there is a much better syntax for that than is suggested in the introductory materials
auto param_value = declare_parameter(...);
