Py0y

Py0y is a fictional, open-source programming language and runtime used here as an example to illustrate wiki-style documentation. It is designed to resemble Python in readability while exploring features common in modern language design.

Origin and naming: The project is described as community-driven and hypothetical, with development framed as an educational exercise rather than a production project. The name combines "py" (for Python) with "0y," symbolizing zero-cost abstractions and novelty.

Design goals: Py0y aims for approachable syntax and safety, with strong interoperability with Python ecosystems via a bridge library. It offers optional static typing with type inference, and a focus on safe concurrency and predictable performance.

Features: The language syntax is Python-like, with optional type hints. It supports asynchronous programming through async/await, lightweight tasks, and a small, batteries-included standard library for IO, data processing, and networking. The runtime is a JIT-compiled VM called Py0yVM.

Implementation and architecture: Py0y is presented as cross-platform, running on major desktop and server environments. It includes a front-end compiler, a Py0yVM back-end, and a bridge to CPython for seamless library use. Modules may be written in Py0y or Python.

Development and status: Released under an MIT-style license on a public repository, Py0y has a small but active community. It is mainly used in academic contexts and toy projects to illustrate interpreter design, rather than as a widely adopted production language.
