Web2 days ago · The version we have in C++23 has this too, it calls them fold_left_first and fold_right_last. This lets you simply write: std::ranges::fold_left_first(rng, f); Much better. fold_left_with_iter and fold_left_first_with_iter. The final two versions of fold which are in C++23 are ones which expose an additional result computed by the fold: the end ...
