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.

class Cell {
  var x: int

  method init(v: int)
    requires acc(x)
    ensures acc(x) && x == v
  {
    x := v
  }

  method set(v: int)
    requires acc(x)
    ensures acc(x) && x == v
  {
    x := v
  }

  method get() returns (v: int)
    requires acc(x)
    ensures acc(x) && v == x
  {
    v := x
  }
