OCaml developers debate list invariants and reversed construction

By PulseAugur Editorial · [2 sources] ·

A discussion on the OCaml programming language has emerged regarding the management of list invariants, particularly concerning the common practice of building lists in reverse and then reversing them at the end. This practice, while often localized and manageable, can lead to the proliferation of "reversed" functions like rev_append and rev_map. Antonin Décimo, an OCaml contributor, proposed a method to track the construction order within the list's type itself to maintain stronger invariants, a concept explored by the Cargocut collective with their nel package for non-empty lists.
