Luna is an expressive, minimalistic, elegant programming language implemented in C. With cooperative thread concurrency at its core, async I/O, and influences derived from languages such as Lua, io, Rust, Ruby, and C. Luna favours unification and minimalism over minor obscure conveniences, providing the true convenience of a simple effective language. This includes omitting features which facilitate magic such as getters/setters, method_missing-style delegation etc. This project is very much a work in progress, as I explore the wonderful world of VMs! feel free to join.
