Yeah. I wouldn't use Rust as a scripting language for that reason. But some critical applications want that enforced correctness and (hopefully) proper performance to be guaranteed if you pass the compiler.

I want to eventually join the "50 engines for every game" race that is rust gsme engineer development, but I'm sure not going to have the fast iteration part of design be done in Rust. The renderer and all the managers should be absolutely solid, but some parts of games need you to break stuff quickly.
