It’s a version of a for loop that is evaluated at compile time (or, at least, can be evaluated at compile time if the arguments can also be evaluated at compile time). I couldn’t easily find a reference to Zig’s inline for (both words are common on the Internet, and even in combination with Zig find a lot of unrelated things), is that the same?
I really like this general construction. I’ve done something similar to this with a recursive template, but specialised for a specific use. Their version is a generic template that takes a constexpr lambda (or any other constexpr object with a constexpr call-as-function overload, though lambdas will be the most common).

Yes, sounds right. I’m still getting used to it, but several times I’ve revisited old code and noticed something I could clean up by using inline for.
Edit: Just saw a good example of it in another post on here.
