I started this about 9 years ago and never finished it. The idea comes from a course in my telecom degree called "Señales Aleatorias y Ruido" (Random Signals and Noise), I spent so many evenings writing probability by hand, and every time I wanted to check a result with a computer it was a ton of boilerplate.

The engine is Rust, the JIT is built on Cranelift, there is also a WASM backend so everything runs in the browser too.

Full disclosure, I could only finish it now because of AI agents. In my experience they are amazing at the runtime and the numerical code, but pretty bad at language design, so I kept that part for myself.

It's a toy language. Ask me anything!

Definitely going to play around with this, thanks for posting.

I know MCMC isn’t your goal, but seems like this could be used for ABC-MCMC (as is?)

Would also be nice to have an option to plot using a KDE vs histograms.

(Also your FM example seems to be technically PM)
