You can simply use the Symbol.iterator property to configure how you want the
property and value of the object to be iterated. This will allow you to use any
from of iteration; e.g. For loop while loop forEach if you do the generic way
I'm thinking .

Clarify:
My previous post was not that clear. That post display what I would like to do
in the language. Here is the actual code if I choose to do it as the language
is now:
var i = 0, n = 5;
l2: do {
i += 1;
l3: do {
if (ihttp://jsperf.com/block-scope-vs-function-invocation";>
jsprf to fu
I like to use what the language already have so if we can denote the type by
constructor:
Function foo(a=Number(64),b=String()){
return b+a;
}

Meant the method of the array not the array m itself:
array["push"&&"unshift"].bind(array);

Surprise that I can't do arr1.forEeach(arr2.push);
Will throw an error.
Using bind as:
push = arr2.bind(push);
arr1.forEeach(push);
Works... And not work. Seem to push individual elements and after every second
element, it'll push the hold array.. And after and before each index that hold

Oh wow that seem like a lot of work the interpreter is doing...
Thank you for the explanation guys/gals.
