Implementation
The following is the current implementation of this function.
naturalSort = lst:
let
vectorise = s: map (x: if isList x then toInt (head x) else x) (builtins.split "(0|[1-9][0-9]*)" s);
prepared = map (x: [ (vectorise x) x ]) lst; # remember vectorised version for O(n) regex splits
less = a: b: (compareLists compare (head a) (head b)) < 0;
in
map (x: elemAt x 1) (sort less prepared);
