Revolutionary technologies of the '80 make me appreciate modern programming languages and especially tooling much more.

In general, ‘classes’ declarations were done with macro. I don’t remember the exact code — something akin to

BEGIN_CLASS(A, Parent);
CLASS_MEMBER(a...)
END_CLASS();

The project had started before C++ existed, and the switch would be too costly. It’s not just OOP part, also reflection mechanism with bindings to the homemade scripting language, and multi-platform UI library. It was a gem of its time.

I was working on a C code base with classes, inheritance, and polymorphism, all done by hands and macros.

Something like

typedef struct s_some_class {
    void (*method)(this *s_some_class);
} t_some_class;

Overall, learning C was the best enabler in my whole career. For instance I was learning Python by tinkering with CPython VM, so when I see these ‘WAT’ quircks I know exactly what’s up.

This is my new busyness e-mail signature.

I volunteer in my free time so that more Russian occupiers will be eliminated. I’m very proud of myself.

Indeed, those are anti-tank mines, absolutely harmless to humans.
