Here's a more compact encoding of D/C++20-like ranges packed into a 2.5 klines single header file:

The file `ranges.hpp` syntaxcheck in 0.3s with Clang 10 on Ubuntu 20.04 on my 6 year old laptop.

compared to std.range or std.algorithm it is very unpleasant to read.

It's C++. Compared to a medium-rare rib-eye, stabbing yourself in the groin with a fork is very unpleasant.

I first I thought it's amazing they could do it just that many lines of code.
After looking at it though they're using the stdlib a whole a lot.
Which I consider cheating ;)

And that's "simpler ranges"... how bad are the ones he thinks are too complicated?
