Let’s look at the C++ code used to test the timing to walk through inheritance and virtual functions. The parent is the class PinOutputAbstract . It represents an output pin on an Arduino: ...

Some degree of "IMO" here, but in C++, multiple inheritance is generally an indicator of flawed design. Don't attempt to transliterate Python idioms to C++. The solution domains are sufficiently ...

Allowing multiple inheritance makes the rules about function overloads and virtual dispatch decidedly more tricky, as well as the language implementation around object layouts.
