It looks more like ActionScript than C++ to me. Below is an example from http://haxe.org/doc/snip/newtonmethod
. Note that variable declarations are

var f0:Float

not

Float f0;

- Gordon

class Newton{

public static function main(){

neko.Lib.println("Enter Starting Point");
var x0 : Float = Std.parseFloat(neko.Sys.stdin().readLine());

neko.Lib.println("How Many Iterations?");
var count : Int = Std.parseInt(neko.Sys.stdin().readLine());

// Initialization of variables
var f0 : Float;
var df0 : Float;
var p0 : Float;
var p1 : Float;

p0=x0; // Initial guess at x0

for(i in 0...count)

{

f0=x0*x0-401; // f(x) = x^2-401 or evaluate sqrt(401)
df0=2*x0;     // f'(x) = 2x (derivative of f(x))

p1=p0-(f0/df0);  // p1=p0-(f(x)/f'(x)) Newton's Method Here

neko.Lib.println("p1 = " + p1);
p0=p1; //switch variables for next iteration
x0=p1; //switch variables for next iteration

}
}
}ess at x0

for(i in 0...count)

{

f0=x0*x0-401; // f(x) = x^2-401 or evaluate sqrt(401)
df0=2*x0;     // f'(x) = 2x (derivative of f(x))

p1=p0-(f0/df0);  // p1=p0-(f(x)/f'(x)) Newton's Method Here

neko.Lib.println("p1 = " + p1);
p0=p1; //switch variables for next iteration
x0=p1; //switch variables for next iteration

}
}
}

Haxe is a C++ "like" language.  It is not ActionScript, JavaScript, etc.
It would be a complete re-write of everything we currently already know and use.

Haxe is unique in that that single C++ like language then can output to navtive apps, SWF,
Silverlight, HTML/JS, etc.  It's not very good at any of them, and the biggest problem with
the language is that it limits itself to the least common detonator of all the platforms it
supports.

AS2 is still well supported (and, surprisingly used) in most outputs.  No reason to move and
essentially invalidate all the work done up to this point in time.  If we change technologies
(HaXe or AS4) we throw out EVERYTHING the community has built up to now.  Sure, we will have
a shiney new product, but nothing will stand on it.
