all_t alias not in cpp20 namespace #1477

Hi, I am just wondering why all_t was not yet adopted to the ranges::cpp20 namespace. It seems the standard defines now this transformation type trait in favour of all_view. Is that on purpose or not yet updated? If so I can also make a PR for this.

Thanks a lot

I think I also encountered those discrepancies:

safe_range -> borrowed_range (https://eel.is/c++draft/range.range#5)
enable_safe_range -> enable_borrowed_range
ranges basic_istream_view only has one template argument, standard requires three (https://eel.is/c++draft/range.istream.view#:stream-extractable)
