Question

Is there any way by which I can define functions my_list, my_cons, my_append which perform similar function as list, cons and append respectively?

Otherwise where can I find the implementation of these functions?

Thanks

Answer 1

For my_list and my_append, the solutions are:

(defun my_list (&rest arguments)
    `(,@arguments)
)

(defun my_append (a_list an_item)
    `(,@a_list ,an_item)
)

(my_append (my_list 'a 'b 'c) 'd)

I’m probably wrong but I dont know any alternative method to make pairs, so an alternative to cons do not seems possible. Still, I’m quite new to the LISP world.
