Zortech C++ was the first C++ compiler available for PCs. I bought it even though I had a Mac, and ran it in emulation, to learn C++. Apple had their AT&T Cfront-based MPW C++ compiler about half a year later I think.
Then Symantec acquired Zortech, and totally destroyed the compiler in version 6, immediately driving everyone to the new Metrowerks just as PowerPC came out.
I wonder why that's something worth wondering about.
Maybe they like it? It's a perfectly reasonable systems language, even if it's not my personal favorite. It might be something questionable if they used Fortran or Algol-68, sure.
I think it's a fair question to ask; what particular qualities of D drew them off the beaten path for this kind of task?
Now, I know the answer as a former D acolyte - it's an interesting language with powerful abstractions, albeit hobbled in some ways - but most people don't, so I think it a reasonable question to ask.
I guess the way I read it was my like "why would you choose D when Rust and Zig exist"...but you're right, it could have been a perfectly curious question.
You're really pettyfogging simply to be contrarian. C is a language with a large and active community, and is still the most common/popular language in its fields. Algol-68 and Fortran are not. It has nothing to do with age of the language and everything to do with modern-day usefilledness.
The fact that you're unable to distinguish the difference means you're being purposefully obtuse and annoying or are simply naive.
