True, but as I understand it the Linux approach is to use C
structs to mimic some class type behaviour. Essentially
binding data and functions inside a struct. Is that not the case?
What I was referring to was the lack of any kind of class
structure at all, a purely prototype driven OOP style.
My first OOP project was in pure C and used a combination
of structs and a function protocol to identify objects, it was
mostly modelled on ADA and had no inheritance mechanism.
The concept got refined into an intenal OOP dialect of C
called Cellular C (if I recall correctly) which did have a class
type concept (the cell, of course!) before we eventually

I agree, C++ - especially in its post v2.0 forms - has

All true and the reason I've mostly given up
programming in C++! Indeed one of my biggest fears
for Python is that I see worrying signs that people are
trying to cram in every programming fad going and there
is a danger that it too acquires the kind of baggage
that C++ has gathered over the years.
