That's from jQuery 2.1.3.

And from the same place:

	function cache( key, value ) {
		// Use (key + " ") to avoid collision with native prototype properties 
(see Issue #157)
		if ( keys.push( key + " " ) > Expr.cacheLength ) {
			// Only keep the most recent entries
			delete cache[ keys.shift() ];
		}
		return (cache[ key + " " ] = value);
	}

That's after looking through about 1/10 of the library.  I'll bet there 
are more.  I'll also bet this sort of thing appears in every single 
major library out there.
