: Last I checked, Scheme was a very close Lisp variant. Now, Lisp has pointers
: and pointer operations (CAR, CDR, RPLACA, RPLACD, ...). Doesn't Scheme?
However car, cdr, etc... implement their operations is a non-issue,
what matters is what we are made to see -- and in this case, we never
need to know that pointers are being dereferenced behind the scenes.
This entire genre of operations is abstracted away from us, we are
given a view of lists. This is what I meant by "dereferencing". I
explained this in a previous post, but only after I managed to cloud
the issue (I have a gift for being vague at the worst possible
moments).
In any case I hope I made things clearer.
