Do you have thoughts on how to avoid that? The C++ Core Guidelines seem silent on the matter -- this might be worth raising with the authors.


I have an idea to avoid trivial set/get methods: Flag public data if it is modified internally. This could serve as a heuristic for pre/postconditions on that variable. 
In general one could resolve all data-dependencies inside the class and figure out if a private variable would need to change if a public variable got changed. But that is way more complex!

Still worth asking the authors.
