"Easily" is a stretch, for sure, but John Wainwright developed a framework that he called "oic", for "Objects in C", that was a fairly substantial subset of CLOS. I met him at OOPSLA ‘89 (or it might have been at AAAI) and introduced him to a couple of Apple developer guys, because I thought oic was cool. Whether because of that introduction or other reasons I’m not aware of, John ended up selling oic to Apple for use as the basis of the ScriptX object system, which was the programming language of the Kaleida Media Player (https://en.wikipedia.org/wiki/Kaleida_Labs https://en.wikipedia.org/wiki/Kaleida_Labs).
