A new language has been created by the AFD Research Academy called ''Cot Hoffy". It's influenced by JavaScript, but uses pure HigherOrderFunction''''''s (HOF's) for its root homoiconic structure (see HomoiconicFaq). "Everything is a HOF from head to toe", says Cutty Wardingham, language project lead. 

Example:

  // add a + b
  function{function, function{(a)}{   
     function(function{function(b)}, function(
     {{function.add()}}, function(), function())
  }
  //
  // short-cut syntax:
  //
  f{f, f{(a)}{   
     f({f(b)}, (
     {{f.add()}}, f(), f())
  }
