Yes. Just use the “better C” mode

It's like saying "C is no longer C if you don't link with libc", it just is not true at all, and honestly, a pretty stupid thing to say

Instead of being an ass, maybe you can take the time to educate me why you think I'm wrong?

I think that at least the garbage collection not being available qualifies my statement as somewhat being true. For game development, as it's closer to what grand-parent asked, classes not being usable would also be an issue...

What essential features are missing for you?

For game development? I imagine having to use only structs but not classes would be something that forces a "non idiomatic D" experience. Dynamic arrays sound like something that's very useful for a game. I don't know, there are plenty of features that are incompatible with better C that makes D, D. Generally speaking, garbage collection would be the biggest in my opinion.

You can still use classes in BetterC - you just have to allocate them yourself. D recently acquired "placement new" which makes that more convenient.

Yeah this person is asking how to make the smallest executable. They don’t want garbage collection.

Garbage collection was about what I would be missing. I mentioned before what could be missing from OP's point of view.

Ok. I think the better C mode is cool and I think it’s worth a try for his interest and project.

I fully agree with you, but I think that if you present it as an option to somebody you should write a line or two about the potential downsides, so they have a better picture. Sorry if I was too abrupt in my criticism of your post. :)
