arrays, focusing on properly declaring in D functions from C

Great article as always!
Maybe this article and conversation revives the interest in a
very much related area: array mangling still doesn't work for
extern(C++).
Example:
---
extern(C++) void foo(int[] arr);
void main()
{
foo([1, 2]);
}
---
// Internal Compiler Error: type int[] cannot be mapped to C++
There have been multiple attempts to fix this, the latest one is
https://github.com/dlang/dmd/pull/8120.
Now, that dmd comes with the (experimental) -H flag for C++
header generation, maybe there's more interest in making D
arrays/strings work seamlessly between D and C++?
