And if you like Lisp and ownership, there's also Carp [1]. It doesn't mimic Rust's features and naming schemes though.

Carp is about 10 years old and has some cool demo's (like SDL for gamedev).

> The key features of Carp are the following:

> * Automatic and deterministic memory management (no garbage collector or VM)

> * Inferred static types for great speed and reliability

> * Ownership tracking enables a functional programming style while still using mutation of cache-friendly data structures under the hood

> * No hidden performance penalties – allocation and copying are explicit > * Straightforward integration with existing C code

> * Lisp macros, compile time scripting and a helpful REPL
