Follow up to episode on better main #255
Description
Here is a fully lazy way to do the span of string_views that doesn't require any heap.
#include <span>
#include <ranges>
#include <iostream>
int main(const int argc, const char *argv[])
{
for (auto param : std::span(argv, argv + argc) | std::views::transform([](const auto *c_str){ return std::string_view(c_str); })) {
std::cout << param;
}
}

std::views::counted:(Check that codegen is identical on Compiler Explorer)
