Not "item", but "contains", yes.  It breaks websites.  See thread at 
<https://mail.mozilla.org/pipermail/es-discuss/2014-September/039717.html> 
and following.  This is why ES6 ended up with Array.prototype.includes 
instead.

Having "contains" on an Array subclass would not run into that problem 
with Mootools, of course.
