Might be a bit off topic.

In the current filsystem.hpp source code we see e.g.:

// 30.10.8 class path
class GHC_FS_API_CLASS path

Here the 30.10.8 is referring to the C++17 standard paragraph, though in:

• C++20 standard the paragraph is 29.11.7
• C++23 draft standard the paragraph is 29.11.6

Maybe a solution would be:

• to refer, in this case, to [fs.class.path]
• or mention at least that the numbers are derived from the C++17 standard

similar for the other mentioned paragraph numbers.
