When exploring the docs for the standard library, it’s frustrating to have an idea and look for the answer only to find out that an entire module (or package) has been deprecated _after_ I click on it. 

Can we have links to deprecated items on the Standard Library’s TOC page flagged?  

I see you’re using multiple CSS classes on some links.  I propose: 

- add a CSS class to flag links to deprecated items
- use something like the following CSS


----

/*
 * Example 1: color 
 */
.toctree-wrapper a.deprecated {
    color: #933;
}

/* 
 * Example 2: "badge" 
 */
.toctree-wrapper a.deprecated:after {
	display: inline-block;
    content: "deprecated";
	margin: 0 1em;
	padding: 0 1ex !important;
	border-radius: 			1ex !important;
    
	font-size: x-small;
    
	background-color: #f66;
    color: #933;
}

----

Of course, since the CSS class '.deprecated' already exists, there's 2 options: 

1. the examples above are rewritten to use a different classname, or 
2. add the following CSS:

----

/* "Reset" .deprecated in a toctree context */
.toctree-wrapper a.deprecated {
    background: none;
	border: none;
	padding: 0;
}

/* << insert above example CSS here >> */

Are you talking about http://docs.python.org/3/library/index.html ?
That might work for whole modules, but not for classes/methods/functions.
An easy fix for modules would be to add (deprecated) right in the title so that it's visible in the index and also in the Google results (and doesn't require changes in the CSS).
