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.
Nice! I’ve dabbled with something similar on my own lately (originally wrote/vibed to explain some concepts that came up when discussing D&D) at diceplots.com - different approach, keeping the distributions exactly analytical at every step, never sampling.
My system is blocking that site as it is on the HaGeZi blocklist. I don't have any further information, and I'm not expressing an opinion on the site. An alternative might be https://noiselang.com, which is not on the blocklist.

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)

It might be worth looking into probabilistic programming languages. I'm out of date, but I remember webppl, stan, anglican, pymc (a python library).
Seems worth an investigation and maybe mention on the article.

Reminds me of Haskell’s monad-bayes: https://monad-bayes.netlify.app/
oh! that's awesome, i had no idea haskell could express this things
This reminds me of https://mc-stan.org
