Does ActionScript3 provide a list of concepts or lambda calculus?
I am porting some code that I prototyped in python to execute flash, and while ActionScript doesn't suck as bad as I expected (I hear v3 is much better than v2!) There is also something else that I have to make this seem overly prosaic / formulaic, like summing a list ...
var a:int = 0;
for each ( var value:int in annual_saving )
{
a = a + value;
}
return a / 100;
Unlike...
return reduce(lambda x,y: (x+y), self.annual_saving ) / 100
It looks a bit like Java for me (ewe Java: puke! XO ###)
Am I just not aware of the cool3 class summing function? Or does he understand lambda calculus or does he understand a list? or provide some other such short notation? Am I right in suspecting there is a more elegant way to do this, or am I stuck in the 20th century for the remainder of this project !?
Cheers :)

ActionScript is very similar to JS. You could easily implement it yourself if you had to:
var annual_saving = [50, 100, 50, 100];
function reduce (f, arr) {
var a = arr[0];
for (var i = 1; i < arr.length; i++) {
a = f(a,arr[i]);
}
return a;
}
var res = reduce(function (x,y) { return x+y }, annual_saving);
You can easily extend this ... the syntax will be somewhat less attractive, but still very concise.
It doesn't use lists, but it does support anonymous functions and locks. You also have map and filter in Array class.
