A language without hash tables isn't necessarily a lisp. C doesn't
have hash tables, yet by your logic it is a lisp.

Semantics has nothing to do with it. My arguments were not with
respect to semantics, and if you had bothered to pay attention
you would know this.
: > CAR returns the _contents_ of the first slot, CDR the second.
: "Returning the contents of" is "dereferencing". That's what the word
: means, taking a reference to an object and returning the object itself.
: Whether the words you use are "a slot containing an object" or "a pointer
: to an object", semantically the operation is the same one.
^^^^^^^^^^^^
Again since I'm not talking about semantics, your passage is irrelevant.

Pointers as defined in a previous thread which you obviously didn't
read.
Suggestion: Read that thread.
