Dynamic Functions Thing

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.

Sure I could use ()'s and just call the function that way, just thought it would be cool for it to call the function instead of returning the 'name' of it instead.

Would be kind of nice since you could use it just like a variable. It would make it easy to have options that you could have a function for or a constant variable.

No, this is wrong.

Having a constant function automatically be evaluated when coerced to a string doesn't reflect the reality and also provides some more confusion for anyone trying to learn.

Functions are functions, functions are values, but functions are not fully-evaluated values. Anything suggesting otherwise will be misleading.
