F#:
List.init 4 (fun _ -> [])
[for _ in 1..4 -> []]
Or any sane language that uses immutable values by default like Elixir, Erlang, Clojure, Racket, Scheme, OCaml, etc.
> Actually, if you really want to have re-evaluting (sub)expressions, then Python does give you an option: comprehensions.
That's the complaint, that [[]]*4 is not shorthand for list comprehensions and that it's something entirely different. This is common in Python where two things you'd expect to be the same are indeed different in subtle ways.
List comprehensions in Python are closer to sane, but they still have unexpected behavior because of the way scoping works in Python.
