I hope that you are kidding. If you're not, I hope that you have
nothing to do with the "development" (or hobbling) of Emacs Lisp.
Most languages that I know provide list operations without
loading a library. There would be no reason not to. List
operations are fundamental.
One should not have to load a package that emulates CL in order
to have the usual and expected list operations, and one should not
have to load a third-party library like Dash.
Racket:
> (filter odd? '(0 1 2 3))
'(1 3)
Bigloo Scheme:
1:=> (filter odd? '(0 1 2 3))
(1 3)
Clojure:
user=> (filter odd? [0 1 2 3])
(1 3)
Arc:
arc> (keep odd '(0 1 2 3))
(1 3)
NewLisp:
> (filter odd? '(0 1 2 3))
(1 3)
Julia:
julia> filter( isodd, [0 1 2 3] )
2-element Int32 Array:
1
3
Ruby:
[0,1,2,3].select( &:odd? )
==>[1, 3]
OCaml:
# List.filter (fun x -> x > 0) [0;1;2;3] ;;
- : int list = [1; 2; 3]
elisp:
: (mapcar #'1+ '(0 1 2 3))
(1 2 3 4)
