I don’t know where D fits nowadays and which problem it’s trying to solve.

My experience has been similar - it’s hard to categorize the language.

As a low-level system language like C, C++, Rust, Zig? The garbage collector makes it a hard sell to other people, even though one can opt out of it.

As a higher-level application language like Java and Go? D frequently gives me a “low-level language” feel, but I am not sure why.

As a scripting language? I feel like its type system works against the rapid-prototyping coding style commonly seen in scripts.
