eh, this isn't Rust; it's "Rust +nightly with an unstable codegen 
flag."

Marginal codegen improvements aren't going to turn heavy usage of
dynamic arrays into heavy usage of std.container.array either, so
they're not that relevant to expected performance of real-world
programs in D vs. other languages.
