Once the front end of DMD becomes fully D, I read that the backend will also become D, but then what will happen to GDC and LDC whose backends are C++ IIUC?
The Rust compiler is written in Rust but uses LLVM as a backend, like LDC. I don't know the complexities of linking a D frontend with a C++ backend, but if the Rust team can do it, I'm sure that means GDC and LDC will continue to live on.
