No it isn't about languages implementing missing features, but we still have this experience of reinventing Lisp when writing applications in today's languages.

No it isn't about languages implementing missing features, but we still have this experience of reinventing Lisp when writing applications in today's languages. We may not need to re-invent memory management, but I notice that the Rails framework reinvents part of CLOS with its object lifecycle method handling, and Node reinvents continuation-passing style.
