Rust's richer type system provides relatively little value over other contemporary type systems like those of Python, TypeScript, and C#, while not providing anything remotely resembling an "interactive" development experience (no REPL, incredibly slow compilation, not hotpatching), and imposing the extremely burdensome and completely unnecessary burden of manual lifetime management. Until these flaws are fixed, Rust is utterly unsuitable for rapid prototyping.
