Earlier quoted context omitted.
Well, in the real world we need at least polymorphism and operator overloading, but that is against the core Zig philosophy, so serious GameDev ignores it (which ironically one would think is the biggest core market for low level systems programming). Hence why new GameDev development still chooses C++, and Andrew’s project fails to gain a significant boost in users.
So use Zig to implement Smalltalk. All problems solved.
