Ummmm sorry to burst your bubble, all those languages you mentioned are considered part of the lisp family (I'm not sure what Fennel is, so can't comment), so actually you interpreted Paul's statement incorrectly - he didn't say Common Lisp or Scheme in particular, he said Lisp so was referring to all of them.

For what its worth, he's writing his own Lisps (Bel, Arc), is highly proficient in Scheme (just check out the book On Lisp), and is a true lisp polygot. I can't speak for him obviously but I don't think he has a super strong affiliation _just_ to Common Lisp.
