jQuery selector cache with reset (original: http://eamann.com/tech/selector-caching-jquery/). If commenting, please ping me on Twitter, same username.

$-cache.js

function Selector_Cache() {
	var collection = {};

	function get_from_cache( selector, reset ) {
		if ( undefined === collection[ selector ] || true === reset ) {
			collection[ selector ] = jQuery( selector );
		}

		return collection[ selector ];
	}

	return { get: get_from_cache };
}

var cache = new Selector_Cache();

// get selector
cache.get( '#selector' );

// get selector and reset cache
cache.get( '#selector', true );

Thanks for sharing this. Saved me some time. :)
It might be useful to have a way to flush the entire cache as well...
