Need for (C++20) Contiguous Range

[Per Nordlöw]

C++20 defines

- std::ranges::contiguous_range [1] on top of
- std::random_access_iterator [2]

as specializations of

- std::ranges::random_access_range on top of
- std::random_access_iterator

. A contiguous ranges has all its elements stored continuously 
(adjacently) in memory.

Does anybody know the application for this concept/predicate?
