It would also make the very convenient :input selector more useful. Consider:
var formEls = {};
$(':input',myForm).each(function(){
if(var thisVal = $(this).val())
formEls[this.name] = thisVal;
});
I'm considering that if "this" were an unchecked checkbox or radio
button that it would return false. That is, of course, not how it
would have to work. I'm just theorizing.
