Cyber: A fast, memory-safe scripting language with JIT and fibers

Cyber is a new scripting language designed for speed and ease of use. It combines dynamic and static typing, supports concurrency via fibers, and is memory-safe. The language features a fast VM and JIT compiler, and can be embedded in applications or used as a CLI tool. Benchmarks show Cyber outperforming LuaJIT, Python, and Node in recursive Fibonacci tests. It also offers FFI for C-ABI libraries and automatic binding generation.

Cyber wants to provide fast and delightful scripting.
