What is Geul programming language?

Geul is an open-source language designed for Korean SOV grammar, using particles for argument roles instead of position. Self-hosts to x86-64, rivals C speeds.

How fast is Geul compared to C?

In benchmarks on Intel Ultra 5: 1.3x slower on sieve, 1.45x on fib, 2.77x on bubble sort vs MSVC /O2 C. Crushes Python.

Where can I try Geul?

Browser playground at geul-web.vercel.app/playground. GitHub: github.com/wwoosshh/geul-lang. VS Code extension available.
