When you have methods named `cons` `car` and `cdr` that appear to work in the same way as lisp's methods of the same name it's pretty clear that you're not pretending or attempting to be "novel".
While it _should_ say it's a lisp / scheme, given those it doesn't really _need_ to say that because it's pretty forehead slappingly obvious to anyone who knows what lisp or scheme are.
Even if you don't mention Lisp, people will assume you were trying to make it a Lisp and complain that you didn't follow Lisp precedent. Examples can be found in this very comment section.
