About Boost.Foreach
In C++, writing a loop that iterates over a sequence is tedious. We can either use iterators, which requires a considerable amount of boiler-plate, or we can use the std::for_each() algorithm and move our loop body into a predicate, which requires no less boiler-plate and forces us to move our logic far from where it will be used. In contrast, some other languages, like Perl, provide a dedicated "foreach" construct that automates this process. BOOST_FOREACH is just such a construct for C++. It iterates over sequences for us, freeing us from having to deal directly with iterators or write predicates.
int main()
{
net::io_context ioc;
tcp::resolver resolver(ioc);
beast::tcp_stream stream(ioc);
stream.connect(resolver.resolve("example.com", "80"));
http::request<http::empty_body> req{http::verb::get, "/", 11};
req.set(http::field::host, "example.com");
http::write(stream, req);
beast::flat_buffer buffer;
http::response<http::string_body> res;
http::read(stream, buffer, res);
std::cout << res << std::endl;
