The US government wants devs to stop using C and C++

Because they want to replace them with more corporate-controlled languages.

Just add @safe: after your module declaration, and you'll be safe by default if you don't want to wait until D3.

Also, unlike in Rust, you can opt-out from RAII with int foo = void;, although it primarily has a performance advantage with arrays, not singleton variables (might be also useful for aquiring an RNG seed in a dumb way).
