when using -O2.
#include <vector>
#include <print>
#include <ranges>
#include <string>
#include <iterator>
#include <iostream>
auto main(int,char**) -> int
{
const std::vector<std::string> input = {"World 0", "World 1", "World 2",
"World 3", "World 4", "World 5", "World 6", "World 7", "World 8", "Earth"};
auto output = input
| std::views::take_while([](const auto& n) {std::println("{:10} called:
{}","take_while", n); return n.at(n.size()-1) != '5'; })
| std::views::filter ([](const auto& n) {std::println("{:10} called:
{}","filter", n); return n.at(n.size()-1) != '2'; })
| std::views::transform([](const auto& n) {std::println("{:10} called:
{}","transform", n);return std::string("Hello ")+n+" "; });
std::ranges::copy(output,std::ostream_iterator<std::string>(std::cout,"\n"));
}
Not sure what's going on.
