This article is about using the D compiler's ability to import vanilla C code to compile entire C projects.

This might actually make my life a lot easier compared to how I am currently doing certain things with some of my libraries that need to interoperate with C.

Going to give ImportC a spin there!

That's impressive, i thought the preprocessor wasn't planned, looks like it takes care of it too, i guess it's time to revisit D, C but better

Preprocessing is now fully supported!

There is a question about C23 if you can see [dead] people:

1. We can support it, I suspect no headers will go near it for a while but we can.

2. C23 support actually brings some C semantics closer to D ones anyway...

I guess only a subset of C11 is supported? Is there all of C89?

This is just like Zig's C compiler

Designator-list support has since been added. The multi-layer designators are still to be done, though (they're rarely used, so are a lower priority).
