It will be great if core widget framework support live() function to init newly created widgets

PrevAll order documentation

Here http://api.jquery.com/prevAll/#comment-33411999 guest asks about element order in prevAll function.
So my questions are:
- does inverse order guaranteed
- why this feature isnt documented
example:

.class1 #id1
.class2 #id21
.class3 #id31
.class2 #id22
.class3 #id32
.class3 #id33
.class1 #id4

i'm have a node #id32 and i need first preceeding .class2
so i'm do $("#id33").prevAll(".class2").first()
could i rely on inverse order or once it could be broken

usecase:
2. function onclick(){
3. if(expression == true){
4. $("#myselector").attr("checked","checked");
5. }else
6. $("#myselecto").removeAttr("checked");
7. }
So, maybe better add
$("myselector").toggleAttr("checked","checked");

$.each with null behavior

why behaviour of
1. $.each(null,function(){alert(1)})
differs from
1. for(a in null){alert(1)}
jquery raises exception
TypeError: object is null
1. each: function( object, callback, args ) {
2. var name, i = 0,
3. length = object.length, <<-HERE COMES PROBLEM
4. isObj = length === undefined || jQuery.isFunction(object);
we should test is object is null

Hi guys
look
I have <Select> and bunch of options var opts = {1:"a",2:"b"...} got with ajax
and i want to add options in single line
1. $("<select>")
2. .iter(opts,function(i,e){
3. this.append($j("<option>").attr("value",i).text(e)))})
4. .appendTo($(blah-blah))...
mostly same as each
1. jQuery.fn.extend({
  iter: function( object, callback) {
  var name, i = 0,
  length = object.length,
  isObj = length === undefined || jQuery.isFunction(object);
  
     if ( isObj ) {
     for ( name in object ) {
     if ( callback.call(this, name, object[ name ] ) === false ) {
     break;
     }
     }
     } else {
     for ( var value = object[0];
     i < length && callback.call(this, i, value ) !== false; value = object[++i] ) {}
     }
  
  return this;
  });
