I have wondered for awhile now why Rust is getting all this attention of being "Like C but safe and cool!", but no one would mention D. I personally don't do systems programming because I'm not smart enough but the little bit I have done, I found D to be the most-natural feeling (even over Rust), and D has been around a lot longer. I suppose timing is everything for these kinds of things.

D is still build around a GC so it doesn't really fit into a discussion about GC free languages. Unless you want to focus on its "better C" subset, which I think puts it at a disadvantage compared to any language not fundamentally designed around the presence of a GC.

Not to forget, C++ template meta-programming was discovered by accident. That's probably the only feature (and C++ is the only language) that I can think of in any language that's discovered by accident and is of utmost essential for introspection capabilities.

> Not to forget, C++ template meta-programming was discovered by accident. yep, in 1993 some graybeard working on GCC checked files by last modification date to do some refactoring and saw one that hadn't changed since july 7, 1926, aptly called "alexandrescu.c". When he opened it, his computer started glowing yellow and his BSD prompt suddenly changed from '$' to '>'. He executed the testcase associated and the horr…

But that is exactly the point. One should not constrain productivity just based on hypothetical goals, web scale and such similar arguments. Doing the next Fortnite, Crysis or ground breaking AR/VR/Ray Tracing? Sure, every ms/byte counts. Doing a typical Flash like casual game, game prototypes at Ludum Dare, participating at IGF? Having a GC around isn't the biggest concern.

But for those cases, what would move you to use D instead of an entirely memory-safe language like Python or Lua? To justify using D for games, you'd need to find a use-case where speed (e.g. targeting 60fps) is high-priority enough to be writing a lot of low-level code; and yet…

The Rust community is extremely hostile, especially against other languages, and D in particular.

Where do you see that happening? I'd love to tell some people to cut it out!

D is a work of love by WalterBright and the community. I like to think of D as a true successor to C++ when people compare Go to a C++ alternative. It is between Rust and Go but it doesnt do away with Object Oriented programming or the many paradigmns that exist for different programming approaches. I usually tell people if you can grasp C, C++, C# or Java you are going to understand plenty of Go. Rust has a larger l…

I think the optional part might have a bit to do with it. In Java, C#, Go you are 'stuck' with the garbage collector, so people learned to live with it and usually realized it's not as bad as people claim it to be.
