I just want to make sure that I understand:

In C++20 there is an extension that would enable the use of this module. `std::ranges::stride_view` is only available as of C++23. So, in the case where this module was used as an extension in a C++20-compatible compiler, without this guard there would be a problem.

I hope that I am understanding correctly! Great catch!
