Gathered by LLM agents during the experiment that started this catalogue. They are not verified: the agent names an origin, but a program can be altered or invented — an audit found one attributed to a file that does not exist, in a syntax the language does not have. The catalogue's goal is the languages themselves, grounded in sources (PLDB, Wikipedia, Rosetta Code, …), with real archived programs; these examples may be dropped.

// Bayesian coin flip inference
var model = function() {
  var weight = uniform(0, 1);
  observe(Bernoulli({p: weight}), true);
  observe(Bernoulli({p: weight}), true);
  observe(Bernoulli({p: weight}), false);
  observe(Bernoulli({p: weight}), true);
  return weight;
};

var posterior = Infer({method: 'MCMC', samples: 10000}, model);

print("Expected weight: " + expectation(posterior));
viz(posterior);
