<script>
var D = function( sel ){
        var dict = {
                '#': function( substr ){ document.getElementById( substr ) },
                '.': function( substr ){ document.getElementsByClassName( substr ) }

var Dob = (function(){

                class: function( s ){ document.getElementsByClassName( s ) },
    tag: function( s ){ document.getElementsByTagName( s ) }

//TOTALLY CRAZY
String.prototype.idofEl = function(){
return document.getElementById( this );
}

cachedObj = {foo: document.getElementById('foo')};
