This can’t be further from truth. C++ is essentially Frankenstein’s monster.

#12Just what C++ needs, more bloat lol.
C++ is probably the only language that needs a strong style guide, to define a subset you are allowed to use in the project. Linus Torwalds famously said that subset is zero. You're not allowed to use C++ in Linux, a wise move. Here's Google's: https://google.github.io/styleguide/cppguide.html Search for "do not use" and you'll find plenty of hits.

#13Earlier quoted context omitted.
Python is 0-indexed. In OP's example, the start parameter makes i start at 1. Their C++17 example prints starting from 0. Probably a mistake. If you look at the linked page for C++20[0], other types can be put in the initializer statement, so it's unlikely the loop auto-increments.

So, it's just a while loop in a for loop's clothing? That's not going to be confusing for people at all...
No, it's a for loop that happens to include an unrelated variable declaration.

#14Only people who saw nothing bad in passing pairs .begin(), .end() in tons of places in c++ for like 30 years can say that thing like ‘auto&&’ improves anything.

#15I am so happy I haven't written a line of C++ in like 15 years. Absolutely disgusting language. Every time I look up one of their new standards, I'm like how does anyone keep all of this in their head (usually on top of stuff like boost, etc.)? No wonder LLMs are a thing.

#16C++ should copy D's elegance:
import std.stdio;
string[9] vec = [
"the", "quick", "brown", "fox",
"jumped", "over", "the", "lazy", "dog"
];
void main()
{
foreach (i, s; vec)
writeln(i, ": ", s);
}Re: C++20 Improved the For-Loop Syntax
#17C++20 also has an enumerate() generator, so if you like the python syntax you can just do: for (auto [i,v] : std::views::enumerate(vec)) std::cout FWIW C++23 also has a python-like print and println: std::println("{}: {}", i, v);
The enumerate is a better solution than the one in the blog post.
Re: C++20 Improved the For-Loop Syntax
#18Given both Lua and python use a enumerator, the C++ example isn't really the correct equivalent.
for (auto [i, v] : std::views::enumerate(vec)) {
std::cout Re: C++20 Improved the For-Loop Syntax

An articulate creature that hounds its creator for abandoning it?
If anything it is more of a Chimera

And the real monster was the one who created it all along!
