Also, I'd probably personally (out of preference) do that check with
an array like this:
var insertedElements = [];
items.each(function(item) {
var pid = item['pid'];
var stuff = item['stuff'];
if( insertedElements.indexOf(pid)==-1 ) {
new Insertion.Top('body', '<div id="'+pid+'">'+stuff+'</
div>' );
insertedElements.push(pid)
}
});
