Anyway Mike, you know that you can create this function, right?
I don't think that this function is something that will be used often to be
inserted at the core.
To add it:
Element.implements({
enableClass: function(className, isEnabled) {
return (isEnabled) ? this.addClass(className) :
this.removeClass(className);
}
});
The 'return' makes this function chainable.
