Python-shaped syntax.
C++ speeds.

Visuall compiles directly to native machine code through LLVM IR. Classes, closures, f-strings, match statements, generators. All at near-C++ performance with a Pythonic syntax.

Features

Everything you expect from a modern language

Native Compilation

Compiles to native machine code via LLVM with O2 optimization. No VM, no interpreter, no JIT.

Garbage Collected

Thread-safe mark-and-sweep GC with conservative stack scanning and O(1) pointer lookup.

Rich Type System

Static typing with generics, nullable types, isinstance checks, and full type inference.

LSP Server

Diagnostics, completion, hover, go-to-def, references, rename, formatting, inlay hints, and semantic tokens.

Package Manager

Declare deps in vsl.toml, resolve with MVS, fetch from Git. No central registry needed.

Standard Library

math, string, collections, I/O, random, datetime, json, network, and system modules.

Performance

Within 1.0–1.4× of C++ on compute-bound work
