Dynamic Functions Thing

[fowlplay4]

I'm not sure what the correct term is but here's what I think would be cool to have...

PHP Code:

function onCreated() {
  this.testfunc = function () {
    return "Hello World";
  };
  echo(this.testfunc); // should echo "Hello World"
} 


However instead it echos: "function_xxxxxxx_yyyy"

Calling the function instead of returning the name would be so much more useful and fun.
