silly question.
I have a list, say
(setq the_list '(1.0 2.2 5.77 5.0 9))
the length of the list is unknown, until after it is created.
I have been rotating the list.
(setq the_list (append (cdr the_list)(list (list (car the_list)))))
so the above, after my improvised rotate command would look like:
(2.2 5.77 5.0 9 1.0)
unless memory failed me, and I have typos in that last snippet, it works.
now for the silly question.
in such a list, is there any PRACTICAL difference between (car the_list) and (nth 0 the_list)?
:ugly:
FYI
the lists are the vertexes I strip from a LWPOLYLINE, so they are actually pairs, like:
((3126.9 2991.44) (3192.75 3142.98) (2988.14 3177.04) (2969.32 3049.0) (2969.32 3026.68))
that just might matter, but I don't (yet) see how in might matter.
