Dew is a programming language for game scripting with streams. A Dew stream represents something that changes over time, and produces exactly one value per time frame. Dew can be seen as a ML variant with stream as first class citizens.

Features:

• Specifically designed for practical game development
• Highly dynamic stream network to spawn or destroy streams
• Easy integration with game engine with minimal work required
• Statically typed with Hindley-Milner type inference
• Implicit parallelism via asynchronous function calls into game engine
• Uses a garbage collector that is designed with games in mind
• All data structures including streams are immutable
• Communicate with game engine through side-effects of streams
• Compiled to native binary via LLVM

The compiler implementation is a work-in-progress and not available.
