A getter returning by value was mentioned in the OP:
> In C++, it’s common to encounter situations where a member variable needs to be fully controlled by its owner class
> but also readable from outside the class. The typical solution is to define a public getter for the variable:
```cpp
class Foo
{
int value = 0;
public:
int get_value() const { return value; }
};
```
But never mind, if the one returning by reference was already implied as an option in the discussion.

Fair enough.
But with the difference that a classical getter would be by value and that one would return a const reference.

That would be a getter, which the OP was trying to avoid... I guess the OP would like to declare things that looks like 'member fields' but in reality are 'member functions'. Not sure how that would end up though.
