Reindeer

The language specification and runtime can be seen as two separate concerns; similar to how the Python language has been implemented within CPython/JPython, and ECMAScript within V8/SpiderMonkey.

There are multiple implementations (affectionately called "reindeer") of santa-lang, all of which follow the language specification. There is feature parity in-regard to the core language, data types and rich builtin function library.

Implementation	Language	Execution Model

Blitzen	Rust	Bytecode VM
Dasher	Rust	LLVM native compiler
Donner	Kotlin	JVM bytecode compiler
Prancer	TypeScript	Tree-walking interpreter
