So I'm looking at http://wg21.link/p0798 ...

I get that you don't like (nor do I):

std::optional<image> get_cute_cat (const image& img) {
    return crop_to_cat(img)
           .and_then(add_bow_tie)
           .and_then(make_eyes_sparkle)
           .transform(make_smaller)
           .transform(add_rainbow);
}

I'm curious if you would allow the pre-P0798 version:

image get_cute_cat (const image& img) {
    return add_rainbow(
             make_smaller(
               make_eyes_sparkle(
                 add_bow_tie(
                   crop_to_cat(img))));
}
