The point of Walter's argument was not about performance but,
safety guarantees. Guarantees which cannot be given by C, or by
Rust due to it's marking as unsafe (as I understand it). So the
extra info is very useful for the programmer.
Also, I would compare apples to apples here and compile both the
C program and the D code with LLVM.
