Zig Programming Language

From the README:

A delightful, statically typed programming language for writing reliable software. veb features algebraic data types, pattern matching, generics, classes (without inheritance), traits, flow-sensitive typing with type narrowing, trait-driven operator overloading and modules. Ergonomic features such as pipe and concat operators are also supported. Currently, the language runtime executes on a custom register-based virtual machine written in Zig.
