Z2uj

Z2uj is a fictional programming language and its accompanying runtime designed for educational exploration of compiler design and dataflow programming. The language emphasizes readability and modularity, offering a minimal core syntax with an extensible standard library. Z2uj programs combine traditional imperative statements with dataflow expressions to enable parallel execution of independent computations.

The language originated in university coursework intended to illustrate concepts such as lexical analysis, parsing, type inference, and code generation. Over time, Z2uj appeared in textbooks and online tutorials as a teaching tool for operating systems concepts, concurrency, and compiler construction. A reference implementation, Z2uj-Runtime, is described as a lightweight virtual machine written in C that executes Z2uj code on multiple platforms.

Design and features of Z2uj include a small, orthogonal feature set intended to keep the learning curve approachable. It supports a modular module system, first-class functions and closures, and a simple type system with optional type inference. Concurrency is facilitated through lightweight tasks and message passing, allowing students to observe scheduling and synchronization concepts within safe, isolated examples. The standard library provides basic I/O, networking primitives, and utilities for working with collections and streams.

Usage and reception: Z2uj is primarily used in academic settings to teach compiler construction, programming language concepts, and concurrent programming. It is not intended as a production language and has a limited ecosystem of third-party libraries. Nonetheless, it serves as a practical sandbox for exploring foundational ideas in programming languages.
