Michael, what is the fastest way to add element on stack of the list
elements?
Let us say I am adding only strings, would this be faster than `push':
(setq my-list '())
(setq my-list (cons (quote "Word") my-list))
By the way, how do I go to make this right?
-------------------------------------------
(setq my-list '())
(benchmark 1000 (setq my-list (cons "My string" my-list)))
as it gives error that "My string" is invalid function.
Do I need to do something like:
(benchmark 1000 (prog1 nil
(setq my-list (cons (quote "Word") my-list))))
(benchmark 10000000 (prog1 nil
(setq my-list (cons (quote "Word") my-list)))) ➜ "Elapsed
time: 0.823678s"
(benchmark 10000000 (prog1 nil
(push "Word" my-list))) ➜ "Elapsed time: 0.824388s"
So there is no much difference apparently.
