Muninn

A small statically typed scripting language built in Rust.

Muninn parses source, checks types, compiles bytecode, and runs it on a stack VM. The same program can run through the interpreter, bytecode path, hot-reload runtime, or the experimental integer tracing JIT.

Language shape

• Typed functions, bindings, mutation, blocks, loops, and conditionals
• Int, Float, Bool, String, Tensor, Void, and nominal records
• Tensor broadcasting, matrix multiplication, reductions, and eager gradients
• Source checks, bytecode builds, editor support, and runtime metrics

Build, run, benchmark, and inspect every command.
