A hypothetical compositional language

Components.js

component c1 {
  function receive(message: string) { // handles "receive" messages
    print(message)
  }
}

component c2 {
  var running: bool
  function run() {                     // Handles the "run" message
    if(!running)
      running = true
      this->receive("hello world!")   // Sends a message to "receive" with an argument
    else
      this->receive("error!")
  }
}

// An object containing the above components
var x = {
  c1 = new c1()
  c2 = new c2()
}

// send a message to components on x named "run"
x->run() // > hello world!
x->run() // > error!

Objects.js

var x = { } // an empty object
var y = {
  value: "hi" // any value type, not a function
}
var z = Root { // a named object
}

var j = Root { // An object with children
  First {
  }
  Second {
  }
}
for(var child in j) {
  print(child.name) // First, Second
}
j.First.foo() // Get child named "First" send it a message named "foo"
