Oxynium is an open-source programming language I created from scratch Rust. It is a statically-typed, compiled language with a syntax similar to Rust and Go. Some of its features include a powerful type system, anonymous and first-class functions, classes, and operator overloading.

I had previously created Entropy Script an interpreted language with run-time type checking, written in TypeScript, and which inspired Oxynium.
