Qualms?  Do you understand that a list is either
nil (an atom) or a cons?  And that a cons holds
one list element and a pointer to another list?

Now think about _why_ accessing Lisp lists from
the head is different from accessing them from
the end.  To get to the end you need to cdr
down the list, cons by cons - one way or another.

(Or else you have to have saved a reference to
that last cons or its cdr.  In that case you can
get there directly.)

Should one take a different attitude to the two
lane directions when driving down a two-lane
highway?  The "business end" of a weapon or tool
versus the other end?  Qualms indeed.
