Yup. (Was that intended as a correction to something I wrote? If so, I wasn&#x27;t clear enough and I apologize.)<p>Regardless, it may be worth adding that ZetaLisp was one of the most important &quot;source&quot; dialects from which Common Lisp emerged, and that Symbolics people were heavily involved in the process. Genera wasn&#x27;t so far from being &quot;an OS of Common Lisp&quot; even before there <i>was</i> a Common Lisp.
