The optional area argument is the number of the area in which to create
the new list. (Areas are an advanced feature of storage management.) See
the section "Areas" in Internals, Processes, and Storage Management.

zl:copylist· list &optional area Function
This is the same as zl:copylist except that the last cons of the resulting
list is never cdr-coded. See the function zl:copylist, page 115. See the section
"Cdr-Coding" in Symbolics Common Lisp: Language Concepts. This
makes for increased efficiency if you nconc something onto the list later.

copy-seq sequence &optional area Function
A copy is made of the argument sequence, and the result is equalp to the
argument, but not eq. The function copy-seq returns the same result as
the function subseq, when the value of the start argument of subseq is o.
sequence can be either a list or a vector (one-dimensional array). Note that
nil is considered to be a sequence, of length zero.
For example:
(setq name "Bill") => "Bill"
(setq a-copy (copy-seq name»
=> "Bill"
a-copy => "Bill"
name => "Bill"
(equalp a-copy name) => T
(eq a-copy name) => NIL
The optional area argument is the number of the area in which to create
the new alist. (Areas are an advanced feature of storage management.)
