ActionScript in Flash MX is a highly dynamic language.

Nota bene: In ActionScript, functions are objects too and can have methods added to their prototype!

Undocumented Features

On Inheritance

f = function(a, b) {return a + b};
s = "f";
trace(eval(s).apply(null, [1, 2]));
>> 3

The first line creates and assigns a Function object. Function objects have the apply(obj, parArray) method.

NetConnection (used for Flash Remoting) is (?) an XMLSocket object.

chl, 2002-05-01: Even Smalltalkesque methodNotUnderstood-like functionality is there (__resolve is expected to "look up" or construct a fitting Function object and then return it, in this example, we just pass a statically defined function for every method call on our proxy):

FunctionProxy = function () {};
FunctionProxy.prototype.__resolve = function (methodName) {
	trace("So you tried to execute: " + methodName);
	return function () {
		var s = 0; 
		for (x in arguments) {s += arguments[x]}
		return s
	}
}
fp = new FunctionProxy();
r = fp.sayNothingAtAll(10, 20, 30);
trace(r);
>> So you tried to execute: sayNothingAtAll
