How can I remove an event listener once I don't need it anymore?

I found that HTML elements normally provide a removeEventListener method, but how can I do that on the Espruino, especially on the Bangle?

There's similar on Espruino:

• http://www.espruino.com/Reference#l_Object_removeAllListeners
• http://www.espruino.com/Reference#l_Object_removeListener

Eg:

function foo(d) {
  console.log(d);
}
Serial1.on("data", foo);
Serial1.removeListener("data", foo);
