One example: How do we code multiple return values?

In Python: 
- Return a tuple.

In C: 
- Use pointers (evilness)

In C++:
- Return a std::tuple, as you would in Python.
- Use references, as you would in Fortran or Pascal.
- Use pointers, as you would in C.

C++ textbooks always pick the last... 

I would show the first and the second method, and perhaps intentionally forget the last.
