StaDyn (programming language)

StaDyn is a research programming language designed to explore the intersection of static and dynamic typing. Its primary goal is to offer a flexible system where type checking can occur both at compile-time (statically) and at runtime (dynamically), allowing programmers to choose the most appropriate approach for different parts of their code.

The core philosophy behind StaDyn is to provide a gradual typing system. This means that programmers can incrementally add type annotations to their code, transitioning from a purely dynamically typed style to a more statically typed style as needed. This can be particularly useful during prototyping or when dealing with complex or evolving codebases.

StaDyn aims to balance the benefits of both static and dynamic typing. Static typing offers advantages such as early error detection, improved code optimization, and enhanced code readability, while dynamic typing provides flexibility and rapid prototyping capabilities. StaDyn seeks to integrate these advantages into a single language.

Key features often associated with StaDyn include:

• Gradual Typing: The ability to incrementally add type annotations.
• Optional Static Typing: Programmers can choose to use static typing in specific areas of the code.
• Dynamic Typing Support: Support for dynamic typing where static type information is unavailable or unnecessary.
• Type Inference: The compiler can infer types automatically in many cases, reducing the need for explicit annotations.
• Type System with Soundness and Completeness Considerations: Researchers working on StaDyn are often concerned with the theoretical properties of the type system. Soundness ensures that well-typed programs do not exhibit certain runtime errors, while completeness refers to the ability of the type system to verify all valid programs.

StaDyn is primarily used in academic research and experimentation to investigate novel type system designs and programming language paradigms. It is not typically used in production environments. Its development is often driven by research questions related to type theory, program analysis, and software engineering.
